Answer:
The correct answer is A) each of the new double stranded DNA molecules contains one of the original intact strands and one completely new strand.
Explanation:
Semiconservative is one of three types of replication. This particular one takes one original strand from the mother and creates the other one based on the original as a template. When one of the two new chains contains only original material and the other one contains only new material it's called conservative replication. When each strand preserves fragments from the original and creates fragments of new material it's called dispersive replication.
