Explanation:
Given what we know, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.
<h3>What happens when a person's hand is near a flame?</h3>
We can say that the information from the heat being generated by the flame is received by sensory neurons in the person's hand. This information generates a pain response which is integrated as incoming information in the brain, which then produces a motor response to move the hand away from the flame, as an outgoing signal.
Therefore, we can confirm that when a person's hand is near an open flame, the brain is required to integrate incoming and outgoing information. Option C is correct.
