Answer 1

The correct option is D All of the above.

• Cardiac muscle is specialized tissue that is found only in the heart.
• It has characteristics similar to both smooth and skeletal muscle tissue, as well as specialized properties, that allow it to function with fast but sustained contractions, rapid conduction and coordinated movement. Hence, the property of cardiac muscle is involuntary muscles, resistant to fatigue and striated muscle.

So, the correct answer is 'all the above'.
