Answer:

Correct Answer: C

Solution:

The zygospore of Ulothrix, on germination, does not directly develop into a new filament.

Instead its nucleus undergoes zygotic meiosis.

The resultant four haploid daughter nuclei are organised into meiospores which may be motile (meiozoospores) or non-motile (meioaplanospres).
