The correct Answer is:
`(a,b,c)`
Hofmann elimination gives less-substitued alkene.
a. Cope reaction

b. In case of buylky base, Hofmann alkene is formed

c. In case of `RF` (poor leaving group ) whether teh base is bulkyl or non-bulkyl. Hofmann alkene is formed.


`(I)` is more stable due to extended conjugation with `(=)` bond of `Ph-` ring.
