Answer 1

Answer: (A)

Green, Red and Brown

Answer 2

Chlorophyll is a class of pigments found in all photosynthetic organisms. The most important members are chlorophyll a and chlorophyll b which occur in all land plants and are responsible for their green colour. Phycoerythrin is an accessory photosynthetic pigment occurring mainly in the red algae and cyanobacteria. It is a phycobiliprotein, in which the pigmented prosthetic group is phycoerythrobilin, which gives phycoerythrin its red colour.
Fucoxanthin is the major carotenoid brown pigment present along with chlorophyll, in the brown algae.
