Final answer:
The correct option is 4). The telencephalon, or cerebrum, is the brain subdivision responsible for higher cognitive, sensory, and motor functions, hosting the cerebral cortex with its various specialized lobes.
Step-by-step explanation:
The brain subdivision responsible for higher sensory, motor, and integrative functions is the option 4) telencephalon. This region, also known as the cerebrum, includes the cerebral cortex with its specific lobes - frontal, parietal, temporal, and occipital - which control higher functions such as thought, language, emotion, and sensory processing. The telencephalon is a part of the forebrain, and it is significantly larger than the other brain subdivisions, such as the midbrain and hindbrain, due to its extensive role in encephalization, which involves the expansion of the neocortex area responsible for language and consciousness in humans.
