During DNA replication, . a. four identical DNA molecules are produced each parental b. strand serves as a template for the synthesis of a complementary c. strand replication begins at one end of the chromosome and continues d. all the way to the other end one daughter molecule ends up with two newly synthesized DNA strands

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
