Muscle tissue is classified into three main types: skeletal, cardiac, and smooth, each with distinct properties and functions. Among these, muscle tissue can be categorized based on its control mechanisms into voluntary and involuntary types.

Skeletal muscle is typically under voluntary control, meaning individuals can consciously decide when to move these muscles. In contrast, both cardiac and smooth muscle are classified as involuntary since their actions are not consciously controlled. Cardiac muscle, which makes up the heart, operates autonomously to pump blood, while smooth muscle lines various organs and structures, such as the intestines and blood vessels, facilitating processes like digestion and blood flow.

This distinction highlights the varied control mechanisms associated with different muscle types, thus making the statement regarding muscle tissue being voluntary or involuntary accurate. Other options misrepresent the classifications and characteristics of muscle types; for instance, stating there are only two types of muscle tissue overlooks the presence of skeletal muscle, and claiming that cardiac muscle is under voluntary control or that smooth muscle is only found in the heart disregards the complexity and distribution of these tissues throughout the body.
