Answer: (A)

Verified step by step guidance

1. Begin by understanding the types of muscle tissue in the human body: skeletal, cardiac, and smooth muscle.
2. Recognize that cardiac muscle and smooth muscle are both classified as involuntary muscles, meaning they are not under conscious control.
3. Consider the structural characteristics of cardiac muscle: it is striated and typically has a single nucleus per cell.
4. Compare this with smooth muscle, which is non-striated and also typically has a single nucleus per cell.
5. Note that skeletal muscle is the type that is multinucleated and attached to bones, which differentiates it from cardiac and smooth muscle.
