Solution

The correct option is B $C H_{3} - C H_{3} | C | C H_{3} - ⨁ C H_{2}$
Stability of carbocation is explained by the presence of number of $α$ hydrogen.
More the number if $α$ hydrogen more will be the stability.
A is having 3 $α$ hydrogen atoms.
B is having 0 $α$ hydrogen atoms.
C is having 2 $α$ hydrogen atoms.
D is having 1 $α$ hydrogen atoms.
We have seen, B is having the least number of $α$ hydrogen;
Hence, B is least stable
