I think it's B??

Ans 3:

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.

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

Ans 10:

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 11:

Class : Class 8
It’s b

Ans 12:

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

Ans 13:

Class : Class 8
Answer is b as Cornea does not give colour to eye

Ans 14:

Class : Class 7
IT IS OPTION (B)

Ans 15:

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 16:

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

Ans 17:

Class : Class 8
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 18:

Class : Class 8
Answer should be (b)

Ans 19:

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

Ans 20:

Class : Class 8
I agree, it should ideally be B, as iris IS indeed the part of the eye that gives it colour

Ans 21:

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

Ans 22:

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 23:

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

Ans 24:

Class : Class 4

Ans 25:

Class : Class 6

Ans 26:

Class : Class 5
yes you're right

Ans 27:

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