the correct option is C

Ans 2:

Class : Class 2
Answer C is the correct answer as incisors which are present in front most teeth help to bite the food. canines are present just after incisors and help to tear the food. premolars are present just after canines which help to crush the food. molars are present at the last which help us chew and grind the food.

OPTION OF ANSWERS ARE WRONG. SIMMI AND SAMRAT HAVE MADE WRONG STATEMENT

Ans 2:

Class : Class 3
Answer is wrong, Souvik is saying 'avoid' while the answer is giving a different explanation .All Samrak, Souvik and Shivani are wrong.

Ans 3:

Class : Class 6
I think answer is wrong. Shivani is also right. Using a tourniquet prevents the poisoned blood from reaching the heart.

Ans 4:

Class : Class 5
answer is wrong it should be c

Ans 5:

Class : Class 6
answer is wrong because if we apply tourniquet it may damage the nerves. the poison will remain its place but it may kill all the cells there

Ans 6:

Class : Class 5

Ans 7:

Class : Class 7
Answer is wrong

Ans 8:

Class : Class 5
answer is ok.

Ans 9:

Class : Class 5
souvik is saying 'avoid giving water to the person in case of poisoning so the poison does not spread in the body. and tying torniquet just above the wound will spread the poison more. so, the answer should be C

Ans 10:

Class : Class 6
the options are wrong...... even the explaination is wrong

Ans 11:

Class : Class 6
I think answer is wrong , use of tourniquet was preferred method until few years ago , it has been found it can damage blood flow and nerves
