The work done is calculated using the formula:
\[
\text{Work} = \text{Force} \times \text{Distance}
\]
In this scenario, the force exerted is 12 newtons and the distance over which the box is moved is 4 meters. Substituting these values into the formula gives:
\[
\text{Work} = 12 \, \text{N} \times 4 \, \text{m} = 48 \, \text{J}
\]
So, the amount of work done is **48 joules**.
Therefore, the correct answer is:
**D. 48 J**
