MHT CET Chemistry question

Among the following statements on the nitration of aromatic compounds, the false one is

(A)the rate of nitration of benzene is almost the same as that of hexadeuterobenzene
(B)the rate of nitration of toluene is greater than that of benzene
(C)the rate of nitration of benzene is greater than that of hexadeuterobenzeneCorrect
(D)nitration is an electrophilic substitution reaction

Answer: (C)
