Answer:
Correct Answer: D
Solution:
Under unfavourable conditions, a myxamoeba secretes a rigid cellulose wall to form the microcyst.
On the return of favourable conditions, the microcyst wall ruptures to release a myxamoeba.
In the sexual reproduction process, the myxamoebae form clusters.
The central myxamoeba of the cluster engulfs a surrounding myxamoeba to become larger structure which forms a thick wall to form the zygote.
This zygote is called microcyst.
