(D) The rearrangement of $3,3$-dimethylbutyl cation to $2,3$-dimethyl-$2$-butyl cation occurs in two steps: $1.$ $1,2-H^-$ shift: $CH_3-C(CH_3)_2-CH_2-CH_2^+ 	o CH_3-C(CH_3)_2-CH^+-CH_3$ (Primary to Secondary carbocation). $2.$ $1,2-CH_3^-$ shift: $CH_3-C(CH_3)_2-CH^+-CH_3 	o CH_3-C^+(CH_3)-CH(CH_3)-CH_3$ (Secondary to Tertiary carbocation). Therefore,only $1$ hydride $(H^-)$ shift is involved.

$CH_3-C(CH_3)_2-CH_2-CH_2^+ \to CH_3-C^+(CH_3)-CH(CH_3)-CH_3$
How many $H^-$ shifts are involved in the above rearrangement?
