The Correct Answer is A

Circular smooth muscle accounts for the majority of muscle in the stomach and intestine and is the main generator of force for propulsive contractions. There is less longitudinal muscle and it may not be continuous around the entire circumference of the GI tract.

Smooth muscle fibers are coupled via gap junctions allowing low resistance propagation of electrical signals through the fibers.
