• A. They are striated.
• B. They are involuntary muscles.
• C. They are less prone to fatigue.
• D. All of the above

Answer 1

The correct option is D All of the above

The cardiac muscles are present on the wall of the heart. These muscles are striated muscles but involuntary in nature. They are under the control of the autonomic nervous system. Due to the presence of large number of mitochondria, they have the continuous supply of oxygen and hence these muscles are less prone to fatigue.

So the correct answer is 'All of the above'.
