D Correct answer
Explanation

Chlorophyll-a is found in all groups of algae and is the universal photosynthetic pigment. It's the primary reaction center pigment in all photosynthetic organisms. Chlorophyll-b is found in green algae and plants, chlorophyll-c in diatoms and brown algae, and chlorophyll-d in some red algae - but only chlorophyll-a is truly universal across all algal groups.
