Solution

The correct option is C 3
Dehydrohalogenation involves removal of (elimination of) a hydrogen halide by abstracting βH from a alkyl halide in presence of base (alc. KOH) to form alkenes.
Saytzeff product will be major product.

here one of the product is but-2-ene and it can exist as cis and trans form thus two different alkenes will be formed.

Hence total possible alkene that can be formed is three.
