Correct option (c) Chtlamydomonas
Explanation:
In Chlamydomonas, the plant hody is haploid, and represents gametophyle. It reproduces asexually through the formation of zoospores and sexually through gametes. Gametes (haploid) fuse to produce diploid zygote, representing the sporophytic generation The zygote secretes a wall around it to become a resting zygospore (diplod) The zygote and zygospore are the only diploid structure which represents the diplophase.
