Consider the given figure and mark the correct option.
A. Activation energy of forward reaction is `E_(1) + E_(2)` and product is less stable than reactant.
B. Activation energy of forward reaction is `E_(1) + E_(2)` and product is more stable than reactant.
C. Activation energy of both forward and backward reaction is `E_(1) + E_(2)` and reactant is more stable than product.
D. Activation energy of backward reactioni is `E_(1)` and product is more stable than reactant.
