Explanation
To find an answer to the question, you must first understand what an unconditioned reflex is. An unconditioned reflex is an automatic, biological reaction to a particular stimulus that is not needed to be learned or developed over time; it is initially present. Strong environmental, food smell, cut, or other stimulus leads to this instinct behavior, meaning natural, instinctive reactions such as retracting a body part in a sharpe surprise, blinking your eyes, and holding your breath. The CNS -- Central Nervous System -- is composed of two crucial constituents: the Brain and the Spinal Cord. The question asks for which of these two is not commonly participating in the unconditioned reflexes. i.e., not required in initiating and coordinating natural responses. Essentially, much of our potential for reactions to sudden, fundamental stimuli requires basic survival and protection instincts. These responses generally bypass the brain and tend to be regulated and activated by the spinal cord. This is faster since it cuts the brain's way in trying to send rebound signals and turns for immediate survival.
