Solution

The correct option is D All of the above.
Dehydrohalogenation involves removal of (elimination of) a hydrogen halide by abstracting βH from a substrate in presence of base (alc. KOH) to form alkenes.
Since, removal of β hydrogen takes place in elimination step thus it's a β elimination reaction.
CH3CH3|C|CH3Xalc.KOH−−−−CH3C|CH3=CH2+H2O+KX
