Answer 2

Both (A) and (R) are correct but (R) is not the correct explanation of (A).

Option (C) is correct.

Explanation:

Assertion: Some persons have the difficulty to see the objects in dim light

during night.

Reason (R): Cones respond less to the illumination.

Both (A) and (R) are correct but (R) is not the correct explanation of (A).

This is because cones only work in bright light and they do not work in dark.

They respond more to illumination. While rods respond less to illumination and are sensitive to dark changes.
