Why we cannot see colours at night?A)

Iodopsin does not respond to dim light


Rhodopsin synthesis takes time in dark


Iodopsin breaks into scotopsin and retinene in dark


Only one pigment of cone cells is able to absorb light

The correct option is A

The cone cells are responsible for colour vision. These cells contain a photosensitive pigment called iodopsin. It requires high intensity of light for stimulation. Thus, we cannot see colours in the dark light as iodopsin does not respond to dim light.
