Final answer:
Muscle tissue, including skeletal, cardiac, and smooth muscle, can contract and relax, showcasing the property of excitability, which is distinct among body tissues.
Step-by-step explanation:
All three types of muscle tissue share the unique property of being able to contract and relax. The correct option is b) Muscle.
Muscle tissue is one of the four primary tissue types of the body, including skeletal muscle, cardiac muscle, and smooth muscle. All three muscle tissues exhibit a quality called excitability, where they can change their electrical states (from polarized to depolarized) and send an electrical wave called an action potential along the entire length of the membrane. This is essential for muscle tissues to fulfill their role in the body's movement and functionality.
Epithelial tissue covers body surfaces and lines cavities, connective tissue binds and supports body parts, and nervous tissue transmits signals and coordinates the body's functions, but none of these can contract and relax like muscle tissue.
