The Hershey-Chase experiment used radioactive isotopes of sulfur and phosphorus to label protein and DNA respectively, and demonstrated that DNA, not protein, was responsible for carrying genetic information. This helped to prove that DNA is the genetic molecule. Choice A is also correct, as the experiment provided evidence for the semi-conservative replication of DNA.
