Final answer:
The brainstem is responsible for vital life-sustaining functions such as breathing and heart rate. It also integrates sensory and motor information, playing a crucial role in keeping the body functioning autonomously.
Step-by-step explanation:
Your brainstem regulates basic functioning like keeping your heart beating and allowing you to be aware of what's happening to you. The correct answer is c) Brainstem.
The brainstem consists of the midbrain, medulla oblongata, and the pons. It is responsible for vital life-sustaining functions such as breathing, heart rate, and blood pressure.
