(B) The general formula for alkynes is $C_{n}H_{2n-2}$. For $n=5$,the formula is $C_{5}H_{8}$.There are three possible isomeric alkynes for this formula:$(I)$ $CH \equiv C-CH_{2}-CH_{2}-CH_{3}$ (Pent-$1$-yne)$(II)$ $CH_{3}-C \equiv C-CH_{2}-CH_{3}$ (Pent-$2$-yne)$(III)$ $CH \equiv C-CH(CH_{3})_{2}$ ($3$-Methylbut-$1$-yne)Thus,the total number of possible alkynes is $3$.

Number of possible alkynes with formula $C_{5}H_{8}$ is
