Hi friend. The ans is b. It is the hottest planet because of large amount of CO2 in it which causes greenhouse effect. It is true that it reflects sunlight but this is not the reason for it being hot. HOPE THIS HELPS YOU!!!

I agree, it should ideally be B, as iris IS indeed the part of the eye that gives it colour

Ans 2:

Class : Class 8
D

Ans 3:

Class : Class 9
same even i think it should be b bcuz the iris gives colour to the eye and not the retina

Answer is b as Cornea does not give colour to eye

Ans 6:

Class : Class 10
The correct answer is B. Iris gives color to the eye.

Ans 7:

Class : Class 6

Ans 8:

Class : Class 8
IT’S B!! SINCE WHEN DID THE CORNEA BECOME THE PART WHICH GIVES LIGHT??

Ans 9:

Class : Class 8
Answer should be (b)

Ans 10:

Class : Class 9
seriously I am confused.. what should I follow?!?!?!.. The book or this?.. book says that iris gives colour to eyes and online says RETINA?!?!.. my mind is blown.. if this happens in the actual exam marks will be reduced drastically.. I am confused and angry

Ans 11:

Class : Class 8
The correct answer should be option(B) as Iris is the part of the eye which gives its color and not the retina as retina is the innermost part of the eye. But in the solution it is given that retina of the eye gives its color. Iris contains colored pigments which give the eye it s color.

Class : Class 8
It’s b

Ans 14:

Class : Class 9
I think it's B??

Ans 15:

Class : Class 4
Yes the answer is wrong it should be b.iris gives colour to the eye not the cornea

Ans 16:

Class : Class 8
The answer will be option {B} because Iris gives color to the eyes.

Ans 17:

Class : Class 7
IT IS OPTION (B)

Ans 18:

Class : Class 8
I think the given answer is wrong, as it states the correct answer is option D. Option D says Iris does NOT give colour to the eye, but actually, the iris is the coloured part of the eye. Thus, the correct option should be option B.

Ans 19:

Class : Class 5
yes you're right

I have done this test many times, and this issue is still not rectified.. It is the iris which gives colour to our eye and not the retina. Please look into this issue!

Ans 22:

Class : Class 8
Since when did cornea become the part which gives colour? I’m lost ,shouldn’t the answer be b?

Ans 23:

Class : Class 8
Correct answer is B. It is the iris which gives colour to the eye ( not retina)Retina forms the inverted image .

Ans 24:

Class : Class 4
yes the answer is wrong because this states that the cornea gives colour to eyes which is wrong

Ans 25:

Class : Class 8
this answer is wrong correct answer is b

Ans 26:

Class : Class 3
not B? I'm pretty sure the iris gives colour to the eye...

Ans 27:

Class : Class 6
correct is B
