A Correct answer
Explanation

Conservative mode is a postulated type of DNA replication in which double-stranded helix remains intact and acts as a template for a new double-stranded DNA helix. This type of DNA replication is disproved model, in this type of replication one-half of the daughters DNA molecules will have both strands composed of newly polymerized nucleotides and the old parent double stranded helix will remain unchanged.
