Final answer:
The limbic system, including the amygdala, hippocampus, and cingulate gyrus, interacts with subcortical brain structures to give rise to emotions.
Step-by-step explanation:
The limbic system, which includes the amygdala, hippocampus, and cingulate gyrus, interacts with subcortical brain structures to give rise to emotions. One important structure within the limbic system is the amygdala, which is involved in the sensation of fear and recognizing fearful faces. The prefrontal cortex, on the other hand, is not a subcortical brain structure but is involved in regulating emotion and making decisions. Therefore, the correct answer is A) Prefrontal cortex.
