    for Deta E = delta U , there must be delta n must be zero

    eduncle-logo-app

    if moles of reactant = moles of product then delta n = 0

    eduncle-logo-app

    in option a it is also zero as there is 1 mole of co2 and 1 mole of o2

    eduncle-logo-app

    so option C is correct

    eduncle-logo-app
