Answer 1

Answer: (D)

Xanthophyll and carotene

Chlorophyll is the major photosynthetic pigment present in the chloroplast of a plant leaf. Xanthophyll and carotene are the additional photosynthetic pigments which avoid photo-oxidation in photosynthesis. Anthocyanin pigments are often red, purple or blue. These pigments have been said to help a plant against light stress and act to help protect a plant from blue-green and UV light which is found in red/purplish fruits and vegetables, including purple cabbage, beets, blueberries, cherries.

So, the correct answer is option D.
