A
Visceral smooth muscle
B
Cardiac Muscle
C
Skeletal muscle
D
Multiunit smooth muscle
Explanation: 

Detailed explanation-1: -Skeletal muscle cells are long, cylindrical, and striated. They are multi-nucleated meaning that they have more than one nucleus. This is because they are formed from the fusion of embryonic myoblasts.

Detailed explanation-2: -Explanation: Skeletal muscle tissue has the most nuclei out of the different types. Cardiac has one or two nuclei per fiber, and smooth muscle cells only have one. This is because of the high metabolic demands of these cells.

Detailed explanation-3: -Skeletal muscle fibers are striated, multinucleated cells ranging from 10 to 100 micrometers in diameter and many centimeters long. The nuclei are located in the cell’s periphery, adjacent to the sarcolemma.
