Verified by Toppr

The correct option is D trans-2butene.
During the debromination, Br2 molecule is eliminated and a double bond is formed. So there will be two products:
a. Trans-2-butene and
b. cis-2-butene.

The trans product is more stable than the cis one due to the steric effect. So the major product would be the trans-2-butene.

Hence, the correct option is D.
