Correct answer

B. Hershey and Chase

Step-by-step solution

The final proof that DNA is the genetic material came from the experiments of Alfred Hershey and Martha Chase (1952). Griffith's experiment proved the existence of genetic material while Avery, MacLeod and McCarty worked to determine the biochemical nature of transforming principle. Concept enhancer Hershey and Chase during their experiment grew viruses in two mediums, one containing 32 P and other 35 S, when these were allowed to infect bacteria, they observed that viruses containing 32 P DNA were radioactive
