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

Ans 2:

Class : Class 8
Answer should be (b)

Ans 3:

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

Ans 4:

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

Ans 5:

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

Ans 6:

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

Ans 7:

Class : Class 7
correct is B

Ans 8:

Class : Class 7
IT IS OPTION (B)

Ans 9:

Class : Class 5

Ans 10:

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

Ans 11:

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

Ans 12:

Class : Class 8
D

Ans 13:

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

Ans 14:

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

Ans 15:

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

Ans 16:

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 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!

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

Ans 22:

Class : Class 6

Ans 23:

Class : Class 8
It’s b

Ans 24:

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

Ans 25:

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.

Ans 27:

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.

Fruits (2) contain minerals and vitamins and are protective food. They help in recovering from illness. Overeating of fried food (1) leads to obesity as it contains fat that gets stored in the body. Chocolates (3) contain a lot of carbohydrates which give us energy when hungry.
