Solution

The correct option is B 3,3-dimethylbutyne
$C 1 H \equiv C 2 - C 3 (C H_{3})_{2} - C 4 H_{3}$

The numbering of the compound starts from the triple bond carbon, as alkynes are given higher priority in the order of priority of functional groups when compared to alkanes or single bonds, and methyl substituents.
IUPAC name: 3,3 - dimethylbutyne.

Hence, the correct option is B.
