\(G_1-phase\)
\(S-phase\)
\(G_2-phase\)
\(M-phase\)
DNA replication occurs in the S-phase of the cell cycle. This is when DNA is synthesized to ensure that each daughter cell receives a complete set of genetic information.
So, the correct option is (B): S-phase

The sequence of growth and division of a cell, and consists of a series of biological processes, particularly the resting phase (G0), the interphase (G1, S, G2), and cell division (i.e. mitosis and cytokinesis)
