(B) In the cell cycle,the $S$-phase (Synthesis phase) is responsible for $DNA$ replication.During the $S$-phase,the amount of $DNA$ per cell doubles (from $2C$ to $4C$),but the number of chromosomes remains the same.Since the $G_2$-phase occurs after the $S$-phase and before mitosis,the cell contains double the amount of $DNA$ compared to the initial $G_1$-phase.Therefore,if the initial amount of $DNA$ in the $G_1$-phase is considered as $1$ unit (or $2C$),the amount in the $G_2$-phase is $2$ units (or $4C$ relative to the original $DNA$ content per chromosome set).
