The correct response is:

**D** Semiconservative replication, as each resulting DNA molecule is a combination of one old and one newly replicated DNA.

In semiconservative replication, each strand of the original DNA molecule serves as a template for the creation of a new complementary strand. As a result, each new DNA molecule consists of one old (parental) strand and one newly synthesized strand. This model was confirmed by the experiments of Meselson and Stahl in the late 1950s.
