Solution

The correct option is C More the heat of combustion, lesser is the stability of alkenes.
The addition of hydrogen is called as hydrogenation.
The heat released in a hydrogenation reaction is called the heat of hydrogenation ΔHHOH
More the number of π bonds more is the heat of hydrogenation.
More the heat of hydrogenation, lesser is the stability of alkenes.
Heat of combustion : The amount of heat liberated when a given amount of the substance undergoes combustion.
For a given hydrocarbon CxHy, the combustion reaction is :
CxHy (s)+(x+y4) O2 (g)x CO2+(y2) H2O (l)

More the heat of combustion lesser is the stability of alkenes.
More the number of carbon atoms, more  is the heat of combustion.
