Answer

### c. No, the wall did not move

Explain

## Step 1: Define Work in Physics<br />### Work is defined as the product of force and the distance over which it is applied in the direction of the force, mathematically: $W = F \cdot d \cdot \cos(\theta)$.<br />## Step 2: Determine if Work was Done<br />### For work to be done, there must be a displacement in the direction of the force. If the wall did not move, displacement is zero.<br />## Step 3: Relate Exhaustion to Work<br />### Exhaustion of the athlete indicates energy expenditure but not necessarily work in the physics sense, as work requires displacement.
