A	duplication
B	fertilization
C	hybridization
D	replication

Explanation:

Detailed explanation-1: -DNA replication is the process by which the genome’s DNA is copied in cells. Before a cell divides, it must first copy (or replicate) its entire genome so that each resulting daughter cell ends up with its own complete genome.

Detailed explanation-2: -S phase is the period during which DNA replication occurs.
