Solution

The correct option is A $C_{6} H_{6}$ and $C_{6} D_{6}$ react with almost the same rate for most electrophiles
In most electrophilic aromatic substitutions, the first step is slow and the second step is fast. Since the first step does not involve deprotonation, the kinetic isotope effect is not observed in it. Therefore, $C_{6} H_{6}$ and $C_{6} D_{6}$ react with almost the same rate.
