(A) The given compound is $3$-vinyl-$4$-but-$1$-enylcyclopent-$1$-ene. There are two chiral centers in the cyclopentene ring (marked with $*$). Additionally,there is a double bond in the side chain $(-CH=CH-CH_2CH_3)$ which can exhibit geometrical isomerism ($cis$ or $trans$). Therefore,the total number of stereocenters is $n = 3$ ($2$ chiral centers + $1$ double bond capable of geometrical isomerism). Since the molecule is unsymmetrical,the total number of stereoisomers is $2^n = 2^3 = 8$.

The total number of stereoisomers possible for the following compound is:
