Cardiac muscle is
A
Striated/Involuntary
B
unstriated/voluntary
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control. Smooth muscle fibers are located in walls of hollow visceral organs (such as the liver, pancreas, and intestines), except the heart, appear spindle-shaped, and are also under involuntary control.

Detailed explanation-2: -Cardiac muscles are also involuntary muscles but are found only in the heart. Cardiac muscles are branched and cylindrical in shape. They are uninucleate cells. So, option C is the correct option.

Detailed explanation-3: -Both skeletal and cardiac muscles appear striated, or striped, because their cells are arranged in bundles. Smooth muscles are not striated because their cells are arranged in sheets instead of bundles.
