(B) The phenomenon of bacterial transformation was first discovered by Frederick Griffith in $1928$ while working with $Diplococcus$ $pneumoniae$.He observed that a non-virulent strain of bacteria could be transformed into a virulent strain by a 'transforming principle' from heat-killed virulent bacteria.Later,in $1944$,Oswald Avery,Colin MacLeod,and Maclyn McCarty identified this 'transforming principle' as $DNA$,providing the biochemical evidence for transformation.
