IUPAC Name is :-
1-Ethyl-2,3-dimethylcyclopentane
The more substituents the alkenes have, the more stable they are that is the more substituted alkene is most stable.So stability order is :-
iii>ii>i
Most stable carbocation will be formed at Carbon B because at this carbon carbon is tertiary carbocation and it is also resonance stabilise
C31H64 is an example of parrafin wax so option e is correct
