Solution

The correct option is A $A \to$ activation energy, $C \to △ H^{\circ}$
Activation energy is defined as the least possible amount of energy (minimum) which is required to start a reaction or the amount of energy available in a chemical system for a reaction to take place $\to A$ .

$C \to △ H^{o}$ is the difference of the forward and backward activation energies.

Hence, the correct answer is option $A$ .
