Verified by Experts

The correct Answer is:
B
Volvox is colonial green alga. The cells are like unicellular alga chlamydomonoas and are definitely organised in the form of a colony called coenobium. The coenobia of volvox are largest, highly differentiated and well evolved among motile forms. Each coenobium is motile, the movement is brought about by the joint action of the flagella of individual cell.
