Solution

The correct option is C g > a > b = c = d > e > f
Rate determining step of nitration does not involve (C - H) bond cleavage.
$∴ C_{6} H_{6} = C_{6} D_{6} = C_{6} T_{6}$
Nitration is an electrophilic aromatic substitution reaction. The +I effect increases the rate of nitration whereas the -I effect decreases the rate of nitration.
