• B. Chlorophyll a and b
• C. Chlorophyll c
• D. Chlorophyll and d

Answer 1

The correct option is A Chlorophyll a

Algae are grouped into three main classes based on the type of pigments present in them. They are Chlorophyceae, Phaeophyceae, and Rhodophyceae.

Chlorophyceae or the green algae contain pigments chlorophyll a and b, which give them grass green color.

Phaeophyceae or the brown algae, color from olive green to brown because of chlorophyll a, c, carotenoids, and xanthophylls.

The significant pigments present in Rhodophyceae or red algae are r-phycoerythrin, chlorophyll a, and d.

Hence, chlorophyll a is the pigment that is common to all of the algal classifications.
