    B has higher enthapy of 100Kcal from A and it has higher enthapy of 10kcal from C. so order is B > C > A

    option B is correct

    eduncle-logo-app

    On addition of both the equation you will get A = C (20 calories)

    eduncle-logo-app

    A= B 100 calories.

    So If we assume A has enthalpy of formation is zero then C has 20 & B has 100
