The correct option is D Parasympathetic Nervous System (PNS)
If a person faces a scary situation, his heartbeat increases. After a while, the normalcy is restored. The part of the nervous system which helps in restoring normalcy is the parasympathetic nervous system (PNS). The increase in the heartbeat is brought about by the sympathetic nervous system (SNS). The autonomic nervous system (ANS) is a control system that acts largely unconsciously and regulates bodily functions such as the heart rate, digestion, respiratory rate, pupillary response, urination etc. SNS and PNS are the two circuits of the ANS. The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts: the brain and the spinal cord. The brain is the centre of our thoughts, the interpreter of our external environment, and the origin of control over body movements.
