(B) The given compound is $CH_3-CH=CH-C\equiv CH$. According to $IUPAC$ rules,the numbering of the carbon chain starts from the end that gives the lowest possible locants to the multiple bonds. If there is a choice between a double bond and a triple bond,the double bond is given priority for the lower number. Here,the double bond starts at $C-3$ and the triple bond starts at $C-1$. Thus,the correct name is pent$-3-$en$-1-$yne.
