C Correct answer
Explanation

Rhodopsin (visual purple) requires vitamin A for synthesis. Carrots are rich in beta-carotene, which the body converts to vitamin A. Vitamin A deficiency causes night blindness due to insufficient rhodopsin. Tomatoes, radish, and guavas don't provide significant vitamin A.
