The given question is asking about the location of the seat of intelligence in the brain.

Option 1: Cerebrum is the largest part of the brain and is responsible for many higher functions such as thinking, memory, and perception. It is involved in intelligence, but it is not the specific seat of intelligence.

Option 2: The cerebellum is located at the back of the brain and is primarily involved in coordinating movement and balance. It is not considered the seat of intelligence.

Option 3: The medulla is located at the base of the brainstem and is responsible for controlling vital functions such as breathing and heart rate. It is not associated with intelligence.

Option 4: The thalamus is a relay station in the brain that helps transmit sensory information to the cerebral cortex. It is not directly related to intelligence.

Therefore, the correct answer is option 2. Although it is important to note that the idea of a specific "seat of intelligence" is a complex and debated topic and cannot be confined to a single brain region.
