Answer: The answer is A

Explanation: I picked A because both skeletal muscle and cardiac muscle are striated.

The option that distinguishes the smooth muscle from the skeletal and the cardiac muscle is that the smooth muscle is nonstriated.

  • Smooth muscles are also referred to as the involuntary muscles. They contract automatically and slowly. They're not striated.

  • It should be noted that the skeletal muscle and the cardiac muscles are both striated. The cardiac muscles are the involuntary muscle tissue that enables the heart to pump blood.

In conclusion, the correct option is C.
