The Broca's area is located in the lobe:
- A. frontal
- B. parietal
- C. temporal
- D. occipital
Correct Answer: A
Rationale: Frontal lobe is the correct answer because Broca's area, which is responsible for speech production and language processing, is located in the posterior part of the frontal lobe, typically in the left hemisphere. Damage to this area results in Broca's aphasia, characterized by non-fluent speech and difficulty forming sentences.
