Given below are two statements: one is labeled Assertion (A) and the other is labeled Reason (R).

Assertion (A): The muscles located in the walls of visceral organs like alimentary canal are smooth in appearance.

Reason (R): Activities of smooth muscles are not under the voluntary control of the nervous system.

In the light of above statements, choose the correct answer from the options given below.

Assertion (A): "The muscles located in the walls of visceral organs like the alimentary canal are smooth in appearance."

This statement is true. Smooth muscles, also known as involuntary muscles, are found in the walls of organs like the digestive tract, and they appear smooth under a microscope.

Reason (R): "Activities of smooth muscles are not under the voluntary control of the nervous system."

This statement is also true. Unlike skeletal muscles, which are under voluntary control, smooth muscles function involuntarily. The contraction and relaxation of smooth muscles are regulated by the autonomic nervous system, not under conscious control.

So, both the Assertion and the Reason seem to be correct, but the reason does not explain why the muscles in visceral organs are smooth in appearance.
