(D) Alfred Hershey and Martha Chase conducted experiments in $1952$ to determine whether $DNA$ or protein was the genetic material.They used the $T_2$ bacteriophage,a virus that infects bacteria $(E. coli)$.They grew some viruses in a medium containing radioactive phosphorus $(^{32}P)$ to label $DNA$ and others in a medium containing radioactive sulfur $(^{35}S)$ to label proteins.After allowing the bacteriophages to infect the bacteria,they found that only radioactive phosphorus $(^{32}P)$ was transferred into the bacterial cells,proving that $DNA$ is the genetic material.
