Solution

The correct option is C Asexual reproduction; fragmentation
When water and nutrients are available algae grow and multiply rapidly by fragmentation which is an asexual mode of reproduction. An alga breaks up into two or more fragments. These fragments or pieces grow into new individuals. This process continues and they cover a large area in a short period of time.
