Motor speech area (Broca's) is located in which lobe?

Explanation:
The motor speech area, Broca's area, sits in the frontal lobe. More precisely, it’s in the inferior frontal gyrus of the dominant hemisphere and coordinates the muscle movements needed for speech—lips, tongue, jaw, and larynx—enabling the articulation of words. This role in planning and executing spoken language is why the frontal lobe is the correct location, not the temporal lobe (which houses language comprehension in Wernicke's area), the parietal lobe, or the occipital lobe (which handles vision). A lesion here tends to cause nonfluent, effortful speech with relatively preserved comprehension, highlighting its motor role in speech production.
