Answer:
b. the amygdala
Explanation:
In psychology, the amygdala is a part of the brain that is part of the limbic system (the most primitive system) and is responsible for emotions, survival instincts, and memory. Some of the emotions that are controlled by the amygdala are: fear, pleasure, anger and feelings from the past that generated a strong emotional reaction.
In this example every time Alice drives by the hospital where her grandmother died, she thinks of her grandmother and gets emotional when she remembers all the suffering her grandmother went through. Since she is recalling feelings from the past that generated a strong emotional reaction, the brain structure that is responsible for evoking such memories is the amygdala.
