The two compounds i.e Pent- 1- ene and pent- 2- ene, are position isomers as they differ in the position of the position of the double bond only, as we know that the position isomers have same molecular formula but they differ in the position of functional group or a substituent or the position of the double bond.

Hence, option (i) is correct option.
