1,2-Dibromopropane is heated with excess $NaNH X_{2}$ , and the mixture is then treated with water. The final product is

Apropan-1,2-diol
Bpropyne
Cpropene
Dpropane

Answer: B

Two successive dehydrobromination steps convert the vicinal dibromide to an alkyne. Excess amide deprotonates the terminal alkyne to its sodium salt, and water liberates propyne.
