Verified step by step guidance

1. Understand the types of muscle tissue in the human body: skeletal, cardiac, and smooth muscle.
2. Recognize that skeletal muscle is attached to bones and is responsible for voluntary movements, meaning it is under conscious control.
3. Identify that cardiac muscle is found in the heart and is responsible for pumping blood; it operates involuntarily.
4. Note that smooth muscle is found in walls of hollow organs (like intestines and blood vessels) and also functions involuntarily.
5. Conclude that among the options given, skeletal muscle is the only type that is voluntary, as it is controlled consciously by the nervous system.
