The second option is the right one.
For DNA replication to occur, an existing double-stranded DNA (dsDNA) must be “unzipped” to form two strands of single-stranded DNA (ssDNA). The ssDNA then serves as the scaffold onto which a complementary strand of DNA is built by adding nucleotides one by one. At the end of this process, there are two identical strands of dsDNA, which then move into the daughter cells.
