The right option is; it interprets signals from the external environment
The peripheral nervous system (PNS) is made up of all parts of the nervous system, except the brain and spinal cord (parts of the central nervous system). The peripheral nervous system functions as a channel through which neural signals are transferred from and to the central nervous system. Two types of neurons (sensory and motor neurons) functions in the PNS. The motor neurons transfer neural signals from the central nervous system directly to various muscles, glands, and organs (effectors) throughout the body.
I am not too sure about this but

Receptors detect changes in the environment. For a stimulus to elicit a response, certain cells must have an appropriate receptor. Stimulation of the receptor initiates a specific signal pathway.
Well, that is true. That technique has been used to identify the radioactive decays in minerals to date back to when they were formed.
