The ____ branches out from the spinal cord and brain and reaches the extremities of the body.

A Lombok system
B peripheral nervous system
C central nervous system
D reflex system

The correct answer is B) peripheral nervous system.

To arrive at the answer, you need to understand the different components of the nervous system. The nervous system is composed of the central nervous system (CNS) and the peripheral nervous system (PNS).

The central nervous system includes the brain and spinal cord. It is responsible for processing information, coordinating actions, and controlling bodily functions.

In contrast, the peripheral nervous system consists of all the nerves that branch out from the spinal cord and brain and extend to the rest of the body. It connects the central nervous system to the extremities, such as the arms, legs, and organs. The PNS helps transmit sensory information from the body to the brain and spinal cord for processing and delivers motor commands from the brain and spinal cord to the muscles and glands.

Given this information, the correct answer to the question is B) peripheral nervous system.
