The correct option is Option 2) S phase.

During the cell cycle of eukaryotes, DNA replication occurs during the S (synthesis) phase. The cell cycle consists of different phases, including G1 (gap 1), S phase, G2 (gap 2), and M (mitosis) phase.

In the S phase, the cell's DNA is replicated, producing two identical copies of each chromosome. This replication process ensures that each daughter cell receives a complete set of genetic information during cell division. The S phase is characterized by active DNA synthesis, with DNA polymerases synthesizing new DNA strands based on the existing template strands.

Therefore, DNA replication specifically takes place during the S phase of the cell cycle in eukaryotes.
