For SN2 reaction to happen in the given conditions
First alkoxide ions is needed to be prepared
It is prepared by adding base to the alcohol
And then the alkoxide ion attacks the halide
So as we cannot see the options here
Fill the options according to the process
Base is added to the alcohol and alcoxide ion is produced
And this alcoxide ion reacts with alkyl halide to form desired product
I hope this helps if you have any query or want more detailed explanation feel free to ask in the comments section below.
