select one
this muscle type is involuntary.
this muscle type is voluntary.

this muscle type is controlled by the autonomic nervous system.

Explanation:

Skeletal muscle (the exposed muscle supporting bones) is voluntary. Involuntary muscles (like smooth and cardiac) are not under conscious control. Cardiac muscle contracts the heart. Autonomic nervous system controls involuntary muscles. So the key is that skeletal (bone - supporting) muscle is voluntary.

This muscle type is voluntary.
