Arnav Raj Sharma from GEMS International School the ultra master mega, Gurgaon

Ans 16:

Answer is b as Cornea does not give colour to eye

Ans 17:

Satvik Mehta from St Andrews school Bowenpally, Secunderabad
Class : Class 4
Yes the answer is wrong it should be b.iris gives colour to the eye not the cornea

Ans 18:

Antarik Maity from Bharatiya Vidyabhaban, Kolkata
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 25:

Kriday from KDAV, Jamnagar

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

Ans 26:

Bipasana from KV IIT Kanpur, Kanpur

I think it's B??

Ans 27:

Bhramana Roy from Glendale Academy International, Hyderabad
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.
