$DNA$ replication takes place in $S$-phase

(D) The correct answer is $D$. In the somatic cell cycle,the interphase is divided into $G_1$,$S$,and $G_2$ phases. The $S$-phase (Synthesis phase) is the stage where $DNA$ replication occurs,resulting in the duplication of the $DNA$ content of the cell. $G_1$ phase precedes $S$-phase,and $G_2$ phase follows $S$-phase but precedes the mitotic phase ($M$-phase).
