none of these

Detailed explanation-1: -DNA replication is said to be semi-conservative because of the process of replication, where the resulting double helix is composed of both an old strand and a new strand. Each strand of the double helix DNA would serve as a template for synthesis of a new strand.
Detailed explanation-2: -The experiment done by Meselson and Stahl demonstrated that DNA replicated semi-conservatively, meaning that each strand in a DNA molecule serves as a template for synthesis of a new, complementary strand.
Detailed explanation-3: -Semiconservative replication is so named because one of the strands of DNA in each of the two copies of DNA is ancient and conserved while the other is newly produced at the moment of replication.
Detailed explanation-4: -Watson and Crick outlined a model for DNA replication, later called semi-conservative replication. According to Watson and Crick, in preparation for DNA replication, the two strands of DNA first unwound and separated.
