The answer is A. You should Read the book twice again. But even then also you think that the answer is B than the book is a spam. Adaptation is the permanent feature of an organism which helps it to survive in its habitat, while acclimatisation is a temprory feature or change in feature of an organism which helps it to survive in any other place rather than its habitat......................................................................

Pratheek from Null, Null

Acclimatization and adaptation mean two totally different things. Adaptation means permanent adjustment to our habitat whereas acclimatization means temporary adjustment to a place where we temporarily stay for some time and get used to. In my opinion, option A is the right answer.

Ans 1:

Vidush from Dav pakhowal Ludhiana, Ludhiana

No statement 1 is correct where as statement 2 is also correct

Ans 2:

saumil from Prudence, Delhi
Class : Class 5

Ans 3:

Rishi Gopi from Loyola, Trivandrum
Class : Class 9
Statement 1 is false while Statement 2 is true

Ans 4:

Ankit kumar Jha from Ryan International School , Ghaziabad
Class : Class 9
YES THERE IS A LOT OF ERROR IN THE OPTIONS

Ans 5:

Yash Bindal from Global Indian International School, Singapore
Class : Class 9

Ans 6:

Paarth Vashistha from Kunskapsskolan Gurgaon , Gurgaon
Class : Class 8
Statement 2 is correct while Statement 1 incorrect as frictions is defined as a force which opposes motion and it would not be frictional force if it is not opposing motion that why there has to be a option E.

Ans 7:

Yash Bindal from Global Indian International School, Singapore
Class : Class 9
Friction always opposes motion but while drawing a line on a paper, the frictional force acts in the opposite direction in which the tip of the pen acts / the line is drawn. I think all options are incorrect as 'statement 1' is wrong but 'statement 2' is right

Ans 8:

Hprakash09 from Billabong high Bhopal, Bhopal
Class : Class 7
Technically, all of the options are incorrect, as Statement 1 is false and Statement 2 is true.

Ans 9:

Amazing Kids from DPS Panipat Refinery, Panipat
Class : Class 8
Yes , I also agree that friction always opposes motion and the following options are incorrect as *Statement 1* is incorrect and *Statement 2* is correct. There is surely some error.

Ans 10:

ANUBHA MAHAJAN from LOTUS VALLEY INTERNATIONAL SCHOOL, NOIDA
Class : Class 10
not in all cases friction opposes, this is proved from statement 1 as friction acts backward on the paper and it will act forward on the direction where the pencil is moved

Ans 11:

Sarbari Pal from DPS FARIDABAD, Faridabad
Class : Class 5
all the options are incorrect as statement 1 is false and statement 2 is true.so the answer should look like:(iv)none of these

Ans 12:

Ethel shiju from National Public School Indiranagar, Bangalore
Class : Class 9
But friction always opposes motion...then how are they saying that option c is true?

Ans 13:

saumil from Prudence, Delhi
Class : Class 5
In my opinion statement 2 is true and statement 1 is false as friction always opposes the motion of an object. Also the friction between the pencil and paper should be exerted in the opposite direction.

Ans 14:

Student from School, City
Class : Class 8
Friction not always opposes motion, it opposes the relative motion but they should've given examples of it. I have read it in a book but there is no examples there, too. :-?

Ans 15:

Anshuman D from MVM, Hyderabad
Class : Class 9
It should be E first statement is incorrect while second statement is correct.

Ans 16:

Riya Singhani from BVB vidhyashram, jaipur
Class : Class 8
IT 'S ANSWER SHOULD BE D?

Ans 17:

Bharat from Geetanjali Olympiad school, Bangalore
Class : Class 9
I agree with ANUBHA MAHAJAN as friction does not always oppose the motion.

Ans 18:

Arnav Gangwar from DPS NOIDA, GAUTAM BUDH NAGAR
Class : Class 8
Why dont they update the answers and options?? THERE SHOULD BE A NEW OPTION HERE

Ans 19:

Shlok Ghadekar from Tomoae school, Amravati
Class : Class 8
All the options must be incorrect as friction always opposes motion and friction acts in direction opposite of force applied but there is no option saying this

Ans 20:

Aarna Gupta from DPS EAST, BANGALORE , Bengaluru
