Answer 1

Answer: (D)

The members of Rhodophyceae are commonly called red algae because of the predominance of the red pigment, r-phycoerythrin in their body. The food is stored as floridean starch which is very similar to amylopectin and glycogen in structure. Flagellated cells are entirely absent.
