$B. Neopentane$ $"B. Neopentane"$

Explanation:

$Neopentane$ $"Neopentane"$ $\equiv$ $-=$ $C {(C H_{3})}_{4}$ $C(CH_3)_4$ . Here, all the hydrogens are bound to a primary carbon centre. The central carbon is quaternary and bound to 4 carbons.

You should draw structures of the other molecules to verify their connectivity.
