(B) To determine the correct structure of $5-$bromo$-2-$cyclopropylcyclohex$-2-$enol,we follow the $IUPAC$ nomenclature rules:$1$. The principal functional group is the alcohol $(-OH)$,which gets the lowest possible number. Thus,the carbon attached to $-OH$ is $C-1$.$2$. The parent chain is a cyclohexene ring. The double bond (alkene) is given priority over the halide substituent. The numbering should proceed to give the double bond the lowest possible locants,starting from $C-1$ (the alcohol carbon).$3$. If we number the ring such that the double bond starts at $C-2$,the cyclopropyl group is at $C-2$ and the bromine is at $C-5$.$4$. This matches the name $5-$bromo$-2-$cyclopropylcyclohex$-2-$enol.$5$. Looking at the options,the structure in option $B$ shows the $-OH$ group at $C-1$,the double bond between $C-2$ and $C-3$,the cyclopropyl group at $C-2$,and the bromine atom at $C-5$.

$5-$Bromo$-2-$cyclopropylcyclohex$-2-$enol has the correct structure:
