Solution

The correct option is D Brain stem
  • Underneath the limbic system in the brain stem. This structure is responsible for life functions such as breathing, blood pressure, etc.
  • Scientists say that this is the "simplest" part of human brains because animals' entire brains (such as reptiles) resemble our brain stem.
  • The brain stem is made of the midbrain, pons, and medulla.
