Solution

The correct option is A Replication of DNA
One of the most important events in the life of a eukaryotic cell is the replication of its DNA. In order for replication to occur only once per cell cycle, each new round of replication must be preceded by passage through mitosis, or M phase.
Hence, A is the correct option.
