1. The problem asks to choose the correct equation that relates work to force and distance. 2. The formula for work in physics is given by: $$\text{work} = \text{force} \times \text{distance}$$ 3. This means work is calculated by multiplying the force applied to an object by the distance over which the force is applied. 4. The other options (a, b, d) are incorrect because work is not calculated by dividing force and distance or adding them. 5. Therefore, the correct choice is option c: $$\text{work} = \text{force} \times \text{distance}$$
