Q.
Product 'D' is:

1. 
2. 
3. 
4. 

Q. Find the correct option(s) considering the following reactions sequence:


Given: Vapor density of C is 29 and E is anesthetic in nature.

1. F is salicylic acid
2. D on reduction with $LiAl{H}_4$ will give Grain alcohol
3. C on reduction with $NaB{H}_4$ will give simplest secondary alcohol
4. B on reduction with $C{H}_2{N}_2/B{F}_3$ will give anisole
