Solution

The correct option is B A - $G_{1}$ , B - S, C - $G_{2}$ , D - M
During $G_{1}$ phase, DNA content is $2 C$ . S phase is marked by replication of DNA and the amount of DNA per cell is doubled. During $G_{2}$ phase, synthesis of RNA and proteins takes place. During mitosis, DNA content gets equally distributed among two daughter cells.
So, the correct answer is 'A - G1, B - S, C - G2, D - M'.
