Answer:
The correct answer to the question: Which of the following is responsible for preparing the body for defensive action, would be, the sympathetic nervous system (SNS) also known as the Autonomic Nervous System (ANS).
Explanation:
When a person senses that there is danger, or in any way feel threatened by anything, the human nervous system is equipped with the necessary to ensure that this person seeks to protect him/herself from that danger, or face it, if necessary. The impulse that is generated by this ANS is called the "fight or flight" response, and it literally means that the SNS prepares the body, through a series of neurotransmitters, and stimulation, especially the musculo-skeletical system, to respond. There are two ways in which this system will answer to a call of danger or threat, either it will tell the body to flee away from things, or, to face them. In either case, this system will act as an excitatory system for those organs that enable a person to protect him/herself from danger, while it will be inhibitory for those that delay that protective response, like the gastrointestinal system.
