Solution

The correct option is C III only
The diagram represents the various stages of cell division. However, during the meiotic division, when the cells pass from the G $_{1}$ phase to the G $_{2}$ phase, it goes through an intermediary phase the S phase or the Synthesis phase. During this phase of the cell cycle, DNA replication takes place so that genetic abnormalities leading to cell death or diseases are prevented.
So, the correct answer is option C.
