Answer: Option B) each parental strand serves as a template for the synthesis of a complementary strand

Explanation:

In semi-conservative DNA replication,

- a parent double-stranded DNA splits in two.

- Each strand is then read by the enzyme, DNA polymerase, to ensure accurate replication of a newly synthesized strand

- the new strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.

Thus, option B perfectly describes semi-conservative replication of dna
