Solution

The correct option is A 0
The heat of combustion (or the standard enthalpy of combustion) of a substance is the standard enthalpy change accompanying a reaction in which 1 mole of the substance, in the standard state reacts completely with oxygen or is completely burnt. For example, the heat of combustion of CO is represented by following balanced equation.
$C O (g) + \frac{1}{2} O_{2} (g) \to C O_{2} (g) Δ H^{0} = - 283 k J$
