Comment on the statement 'the sum of action and reaction on a body is zero'.

Explanation

To comment on the statement "the sum of action and reaction on a body is zero," we need to analyze the principles of Newton's third law of motion and the nature of action-reaction pairs.

### Step-by-Step Solution:

1. **Understanding Newton's Third Law**:
- Newton's third law states that for every action, there is an equal and opposite reaction. This means that if one body exerts a force on another body, the second body exerts a force of equal magnitude but in the opposite direction on the first body.

2. **Identifying Action and Reaction Forces**:
