the explanation given goes like there are two but they're E and Z stereoisomers so not structural isomers, so there would be only 4 structural isomers in all, then the answer shown is C (5 structural isomers)?

The five structural isomers are listed in the explanation. The drawing for methyl-cyclopropane is missing in the explanation but it basically consists of a three carbon ring with a CH3 group attached to one of the carbons on the ring (CH2CH(CH3)CH2).
