Verified by Experts

The correct Answer is:
`c`
Rate is faster when the substiuent activates the ring (`+I` or/and `+R, o//p`) and the rate is slower when the substituent deactivates the ring `(-1, -R,m)`. Halogen deactivates the ring `(-I, +R, -I gt +R)` b ut the orientation is `o//p`.
Rate of `C_(6)H_(6) = C_(6) D_(6)`, since no kinetic isotope effect is observed when `H` is reaplaced by `D` .
Hence, the same is as given in `(c).(I) = (II) gt (IV) gt (III)`.
