Solution

The correct option is A ${(C H_{3})}_{3} C - B r$
As we know,
stability of carbocations are
$3^{o} > 2^{o} > 1^{o}$

so reactivity of $S N^{1}$ reaction is $3^{0}$ halide > $2^{0}$ halide > $1^{0}$ halide

Option $A$ will form $3^{0}$ carbocation, hence more reactive towards $S_{N} 1$ reaction.
