Answer

Brief Explanations:

The text states that the main difference between the two jack - stands is the way they are locked. One is locked with a steel pin by aligning holes, and the other has a toothed section with a simple mechanical locking system. This indicates a difference in the locking system. Also, the different locking mechanisms imply differences in design. Since both are jack - stands for supporting vehicles, their basic function is the same.

Answer:

A. The design. C. The locking system.
