• B. Chlorophyll $a$ and carotenoids
• C. Chlorophyll $a$ and chlorophyll $b$
• D. Chlorophyll $b$ and carotenoids

Answer 1

The correct option is B Chlorophyll $a$ and carotenoids

Algae contain a wide variety of pigments that absorb light for photosynthesis. The major photosynthetic pigments are chlorophylls, carotenoids, and phycobiliproteins. Chlorophyll $a$ is common to all oxygenic photosynthetic organisms including land plants which, like green algae, also contain chlorophyll $b$
