Answer 1

The correct option is B

Cylindrical cells

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. They have branched shape cell so that each cell is in contact with three or four other cardiac muscle cells. They are striated, like skeletal muscle, as the actin and myosin are arranged in sarcomeres.
