Respuesta :
The correct option is this: EXTENSIBILITY SINCE THE MUSCLES OF THE LEG LENGTHEN AND STRETCH.
The human muscles have four basic properties, which are: contractility, extensibility, elasticity and excitability. Contractility refers to the ability of the muscle to contract. Excitability refers to the muscle ability to generate action potential when stimulated. Elasticity describes the capacity of muscles to go back to its original shape after been extend and extensibility refers to the ability of the muscle to stretch.
