The best answer to the question is: A. The distance jumped is directly related to leg power.
Here's why:
1. In the standing long jump, the distance a person can jump is primarily determined by the power generated by their leg muscles. The more power the legs can generate, the farther the jump will be. This showcases the individual's explosive strength and power from the lower body.
2. Other fitness skills such as balance, coordination, and agility are not the main focus in the standing long jump test. It specifically measures the power output of the legs in a vertical jump movement.
3. While it is true that many power-oriented fitness tests emphasize leg strength, it doesn't necessarily mean that the standing long jump is the only reliable test for leg power. There are other tests and exercises that can also assess leg power effectively.
Therefore, option A is the most suitable explanation as it directly links the distance achieved in the standing long jump to the power generated by the legs.
