Final answer:
Broca's area resides in the frontal lobe and is crucial for speech production, located predominantly in the left cerebral hemisphere for most people.
Step-by-step explanation:
Broca's area is located in the C) frontal lobe. This area of the brain is associated with the motor commands necessary for speech production and is situated only in the cerebral hemisphere responsible for language production. In approximately 95 percent of the population, this is the left hemisphere. Broca's area is essential for language production and is found adjacent to the motor cortex, which is involved in planning and coordinating movement. When Broca's area is damaged, individuals can experience significant difficulties with producing language, which highlights its crucial role in speech articulation.
