Solution

The correct option is B (b)R HC=C R H

More substituted alkenes are more stable, due to the +I effect of alkyl groups, which strengthens the C=C pi bond. This means that it'll be harder to break down substituted alkenes.
Hence, hydrogenation will be easier in the case of less substituted alkenes.
