Final answer:
The correct answer is option D. The mismatched option is D. Medulla oblongata – Temperature regulation since temperature regulation is primarily the function of the hypothalamus, not the medulla oblongata.
Step-by-step explanation:
The question pertains to the functions of different parts of the brain and which option is mismatched in terms of the function and the brain part it is associated with. The correct functions are:
- Cerebrum – Primarily associated with memory, higher cognitive functions, and sensory and motor processing.
- Olfactory lobes – Integral for the sense of smell.
- Cerebellum – Critical for maintaining equilibrium of the body, along with coordination and balance.
However, the medulla oblongata is primarily involved in the regulation of vital functions such as heart rate, breathing, and blood pressure. It is not the primary area responsible for temperature regulation. That function is mainly attributed to the hypothalamus, which acts as the body's thermostat.
Therefore, the mismatched option is:
D. Medulla oblongata - Temperature regulation
