(B) The chemical structure of crotonyl alcohol is $CH_3CH=CHCH_2OH$.In the $IUPAC$ nomenclature,the longest carbon chain containing the functional group $(-OH)$ and the double bond is selected.The numbering starts from the carbon attached to the $-OH$ group to give it the lowest possible locant.Thus,the chain has $4$ carbons,the double bond starts at position $2$,and the alcohol group is at position $1$.The correct $IUPAC$ name is $but-2-en-1-ol$.
