Hyper conjugation occurs in

Hyperconjugation effect is a permanent effect in which localization of σ electrons of C-H bond which are directly attached to an electron deficient radical unsaturated system. For hyperconjugation, the carbons adjacent to electron deficient radical or unsaturated system should have alpha hydrogen. 

i) no $\alpha -$ hydrogen

ii) no $\alpha -$ hydrogen

iii) $\alpha -$ hydrogen
