Solution
The correct option is D Carotenoids
Carotenoids are yellow, orange, or red pigments synthesized in roots, stems, leaves, flowers, and fruit of plants. They take part in photosynthesis. They protect plants that are over-exposed to sunlight. They dissipate excess light energy that they absorb as heat. In the absence of carotenoids, this excess light containing UV radiations can destroy proteins, membranes and other plant molecules. Thus, the correct answer is option D.
