The correct option is A Spindle-shaped, unbranched, unstriated, uninucleate and involuntary
Smooth muscles are found primarily in the digestive tract (esophagus, small intestine, and large intestine), urinary tract (ureter, bladder), etc. The cells are long with pointed ends (spindle-shaped) and uninucleate (having a single nucleus). They are unbranched and involuntary.
So, the correct answer is an option (A) Spindle-shaped, unbranched, unstriated, uninucleate and involuntary
