Solution
The correct option is D EtONa
NaOEt is a strong base. It act as readily as a base than nucleophile due to its relatively larger size and its basic strength.
NaOH and KOH can act readily as both bucleophile and base due to their smaller size.
EtOH is a weak nucleophile/base so it does not readily give E2 product.
Hence, (d) is correct.
