Doubt from hydrolysis

Ans=a

iii will have slowest reaction (negligible) because during SN1 hydrolysis, Carbocation, if formed, will violate Bridt's rule, so iii will be least. For comparing i and ii: endo attack is prefered rather than exo attack (always), so i > ii.

@Lavesh_2020

Correct me if I’m wrong but from what i can remember it’s endo always for right ring and exo for left ring

sir please clear more about the hydrolysis reaction i m thinking i m gooped up in concept...
tell the endo exo concept.. @Shwetanshu_2018 sir.. and @Lavesh_2020..

See you can solve by options also there is no confusing option is given. we know that we cannot form bridge head carbocation so it will be at last.
