To improve the efficiency of a ramp, the best choice would be:
**A. Smooth the surface**
A smoother ramp surface minimizes friction, making it easier for objects (or individuals) to ascend or descend. This leads to a more efficient use of energy and resources when moving up and down the ramp.
Other options, such as adding a rough surface, insulating with foam, or making it shorter and steeper, may not improve efficiency and could introduce other challenges.
