Answer:
C. is a passive process caused by increased intrathoracic pressure.
Explanation:
Inhalation is an active process as it includes the contraction of muscles and diaphragm. Exhalation is a passive stage of breathing. It does not include any muscular contraction. Rather, diaphragm and the external intercostal muscles become relaxed. This reduces the volume of the thoracic cavity and lungs. The reduced volume causes increased air pressure in alveoli as compared to the atmospheric pressure. The increased pulmonary pressure drives the movement of air towards the outside of the body.

The peripheral nervous system is involved in both <u>voluntary and involuntary actions.</u>
Explanation:
The peripheral nervous system (PNS) is the neural system that resides outside the central nervous system (CNS). This contains nerves which in turn connect with the organs of the body like the sensory organs, glands, blood vessels, muscles etc with the central nervous system (CNS).
The PNS is divided into somatic and autonomic nervous systems.
The somatic nervous system contains sensory and motor nerve fibers which send sensory information and controls motor functions respectively. The voluntary movements of skin, skeletal muscles, bones, and joints are controlled by somatic PNS.
The autonomic nervous system composed of sympathetic, parasympathetic and enteric nervous systems controls the involuntary actions of smooth muscles of the internal visceral organs.
