Solution
The correct option is B False
The rod cells contain a photosenstive pigment called rhodopsin, which contains a derivative of vitamin A. Rods enable the organism to see in darkness. Rhodopsin does not give a colour vision. It is senstive to dim light. It gives a twilight vision. Insufficient rhodopsin results in night blindness, due to vitamin A deficiency.
