The correct answer is option A, S Phase - DNA Replication
The DNA replication begin at the S phase of the cell cycle. In this phase, the cell grows and prepare itself for the DNA replication while the other components such as centro some undergo replication. The S phase occurs during the inter phase and the genetic material duplicates itself before entering the mitosis and meiosis cell division in the next stage.
