Answer: (D)

Verified step by step guidance

1. Understand the three main types of muscle tissue: skeletal, cardiac, and smooth muscle.
2. Recall that skeletal muscle is attached to bones and is responsible for voluntary movements, meaning you can consciously control its contractions.
3. Recognize that cardiac muscle is found only in the heart and contracts involuntarily to pump blood, so it is not under voluntary control.
4. Know that smooth muscle is found in walls of internal organs (like intestines and blood vessels) and also contracts involuntarily.
5. Conclude that the muscle tissue primarily under voluntary control is skeletal muscle, as it allows conscious movement of the body.
