Cones work well only during daytime

Text Solution

Verified by Experts

The correct Answer is:
B
Cones operate only in bright light, hence the different types of cones (i.e., blue, red or green-sensitive) are active during daytime or in presence of light.It is because of this reason, that the person is unable to differentiate between green and red colour in night time.
