Broca's area is a region in the frontal lobe of the left hemisphere in the cerebral cortex with functions linked to speech production. Broca's area is located in the lower portion of the left frontal lobe.

The temporal lobe controls hearing. The temporal lobe is located below the lateral fissure on both hemispheres of the brain.

Emotion involves two parts of the nervous system - the limbic system and the autonomic nervous system. The limbic system is a complex set of structures, that lies on both sides of the thalamus, just under the cerebrum. It includes the hypothalamus, the hippocampus, the amygdala. The hypothalamus feeds information into the amygdala. The hypothalamus acts as a regulator of emotion, controlling levels of sexual desire, pleasure, aggression and anger.

The occipital lobe is the visual processing center of the mammalian brain containing most of the anatomical region of the visual cortex. The occipital lobes are part of the forebrain. A significant functional aspect of the occipital lobe is that it contains the primary visual cortex. The optic lobes are especially prominent in fish and birds.

As we move from fish to mammals, there is an observable increase in the brain size relative to the body size. This progressive increase is mainly observed in the form of an increase in the size of cerebral hemispheres or the cerebellum. So, the correct answer is 'Cerebrum'.
