Solution

The correct option is C Only $G_{2}$
In M-phase, both 4C and 2C of DNA are present in different stages. S phase marks the period during which the amount of DNA in the cell doubles. Thus, at G2 phase the amount of DNA is 4C. These doubled cellular contents prepare the cell to sustain in the further mitotic division.

So, the correct answer is option C.
