• A. Sympathetic and parasympathetic nerves and is under involuntary action
• B. Sympathetic nerves and is under voluntary action
• C. Sympathetic and parasympathetic nerves and is under voluntary action
• D. Parasympathetic nerves and is under voluntary action

Answer 1

The correct option is A Sympathetic and parasympathetic nerves and is under involuntary action

Sympathetic nervous system and parasympathetic nervous system are subdivisions of autonomic nervous system. The autonomic nervous system controls the involuntary functions of internal organs such as heart rate, digestion, breathing, urination, etc. The parasympathetic nervous system controls homoeostasis of the body and is responsible for "rest and digest" response. The sympathetic nervous system controls perceived threat responses thus is responsible for "fight or flight" responses. Thus parasympathetic nerves and sympathetic nerves are known to function in relaying information of involuntary functions of the body. So, the correct answer is option A.
