Answer: The correct answer is -
C.S phase.
Step-by-step explanation:
Interphase can be described as one of the two main phases of cell cycle (other being M phase).
It is further divided into three phases that are G1 (gap 1 phase where cell growth occurs and essential factors needed for DNA replication are synthesised) , S ( synthesis phase where replication of DNA takes place ) , and G2 phase (gap2 phase, in which certain organelles divide and cell prepares for division).
Thus, option C) S phase is the right answer.
