Solution

The correct option is B $B > A$
$- I$ and $- B r$ are electron withdrawing group. Therefore, it will decrease the stability of the carbocation.
more is the electronegativity of atom attached to the carbon more it will show -I effect and more it destablise the carbocation. Electronegativity order of atom is Br>I
Therefore, the order of stability of carbocation is:
$(C H_{3} - C H_{2} - C | B r H - + C H - C H_{3} < C H_{3} - C H_{2} - C | I H - + C H - C H_{3}$
Hence B is the correct option.
