Correct Answer - C
`CH_(3)CH=CHCH_(2)overset(**)(C )HBrCH_(3)` is an alkene having different substituents at each carbon atom of the doble bond. So it exists in two geometrical isomers i.e., cis and trans. Since the given compounds also has a chiral centre, therefore, each geometrical isomer has a pair enantiomers. Thus in all, there asre `2xx2=4` stereoisomers.
