Solution

The correct option is B Palmella stage
The palmella stage in Chlamydomonas is formed under unfavorable conditions as a shortage of water, excess salts, etc.
The protoplast of the parent cell divides to make many daughter protoplasts but they do not form zoospores. The parent cell wall gelatinizes to make a mucilaginous sheath around daughter protoplasts. Hence, A Chlamydomonas plant is left exposed in the mud. Palmella stage is a means of survival.
So, the correct answer is "Palmella stage'.
