(C) The transforming principle was first identified by Frederick Griffith in $1928$,but he could not determine its biochemical nature.Oswald Avery,Colin MacLeod,and Maclyn McCarty conducted experiments in $1944$ to determine the biochemical nature of the transforming principle.They purified biochemicals (proteins,$DNA$,$RNA$,etc.) from the heat-killed $S$ strain bacteria and observed that only $DNA$ caused the transformation of $R$ strain bacteria into $S$ strain bacteria.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.

Transforming principle in bacteria is $DNA$. This was first proved through experiments performed by . . . . . . .
