See option B and C anand here given oxidation of carbon and zinc is not feasible but see the reaction given del H is negative.so spontaneous..so it is feasible...so B and C is wrong... Now come to D option...1 mole of Zn oxidation liberates less heat than 1 mole of C liberates..so this is also wrong...option A is correct
got this anand?
This you understand na anand👆
