(B) The correct answer is $B$. Oswald Avery,Colin MacLeod,and Maclyn McCarty $(1944)$ conducted experiments to determine the biochemical nature of the 'transforming principle' observed by Frederick Griffith. They purified biochemicals (proteins,$DNA$,$RNA$,etc.) from heat-killed $S$ cells and discovered that only $DNA$ from heat-killed $S$ cells could transform live $R$ cells into $S$ cells. They also discovered that protein-digesting enzymes (proteases) and $RNA$-digesting enzymes $(RNases)$ did not affect transformation,whereas $DNA$-digesting enzymes $(DNases)$ inhibited it. Thus,they concluded that $DNA$ is the hereditary material.

The transforming principle in Griffith's experiment was $DNA$. It was discovered by:
