Answer:

B. Nitrogenous bases in each "parent" strand serve as a template for the new strand to be made

Explanation:

DNA replication is the process whereby the contents of DNA is doubled or duplicated. In other words, another copy of DNA is produced from one DNA molecule. The process follows the semi-conservative model, which generally speaks of how one template strand is used to synthesize another new strand.

In the semi-conservative model of DNA replication, the double strand of DNA is unwind and one of the strands called parent strand is used synthesize a complementary strand of DNA. At the end of the process, two DNA molecules results with each having one old strand and one new strand. Nitrogenous bases or nucleotides in each "parent" strand" serve as a template for the new strand to be made.
