Smooth muscle cells have a single nucleus and are spindle-shaped. Skeletal muscle cells, on the other hand, are long, cylindrical, and have many nuclei. In addition, smooth muscle cells are not only found in the walls of hollow organs like the digestive system, blood arteries, urine bladder, and uterus but also in the heart. Smooth muscle cells lack the striated appearance of skeletal muscle cells.

Option 1 is the correct answer.
