(B) In the cell cycle,the $S$ phase (Synthesis phase) is responsible for $DNA$ replication. Before the $S$ phase,each chromosome consists of one chromatid (one $DNA$ molecule). During the $S$ phase,$DNA$ replication occurs,resulting in each chromosome consisting of two sister chromatids,each containing one $DNA$ molecule. Therefore,after $DNA$ replication,each chromosome contains two $DNA$ molecules. Since the $G_2$ phase occurs after the $S$ phase,the number of $DNA$ molecules per chromosome remains two.

During the $G_2$ phase,the number of $DNA$ molecules per chromosome is:
