The correct answer is D. **electric forces can act at a distance.**
In this scenario, Jim builds up static electricity by walking on the carpet, and when he brings his finger near the metal doorknob, he experiences a shock due to the electric field generated by the charge imbalance. This demonstrates that electric forces can indeed act at a distance without requiring direct contact.
