Solution
The correct option is A
This problem can be solved by using the concept of nucleophilic substitution reaction, oxidation and reduction reaction including strength of nucleophile and regioselectivity.
Reaction of Scheme 1 can be completed as
Among two nucleophilic group I and II, II is more nucleophilic and then will react selectively as follows.
Hence, using the concept of regioselectivity we come on the conclusion that final product is correctly represented by structure.
