Answer: D) Muscle length

Explanation:

Muscle length determines its ability to produce enough strength for the task that requires it. This is so because, in human anatomy, the muscle has various types of muscle fibers. Some are longer and others are shorter. However, the optimal distribution of these fibers over the muscle (that is, that their different lengths are balanced) will make it possible to concentrate the necessary force.
