In the reversible reaction of the type `A+B hArr AB`, in general.

Options

A. Neither of the reactions will be endothermic.
B. Both forward and backward reactions are exothermic.
C. Forward reaction will be exothermic.
D. Backward reaction will be exothermic.

Explanation

To solve the question regarding the reversible reaction \( A + B \rightleftharpoons AB \), we will analyze the nature of the forward and backward reactions in terms of energy changes.

### Step-by-Step Solution:

1. **Identify the Reaction**:
The given reaction is \( A + B \rightleftharpoons AB \). This indicates that reactants \( A \) and \( B \) combine to form product \( AB \), and this process can be reversed.

2. **Understand Bond Formation and Breaking**:
