As the DU (degree of unsaturation for C5H10 is 1).

It can either be a ring or with one double bonded.

Since for cyclic compounds,

The isomers are:

Cyclopentane
Methylcyclobutane
1,2-dimethylcyclopropane .

The answer came to be seven as the isomers who are optically active have two enantiomers and there are 2 cyclic structures which are optically active so answer is seven...
