The correct option is B true, true, correct explanation
Statement I: Above reaction is exothermic as the energy of products is lower than the energy of reactants.
Statement II: Energy difference B is greater than energy difference A as the energy of products is lower than the energy of reactants.
The energy difference B corresponds to the difference in the energy of products and transition state.
Energy difference A corresponds to the difference in the energy of transition state and reactants.
Both statements are true and second statement is correct explanation of the first statement.
