Final answer:
The left frontal lobe of the brain, specifically Broca's area, is most likely to be involved with language production.
Step-by-step explanation:
The area of the cortex most likely involved with language production is Broca's area, which is located in the left frontal lobe of the brain. This region is associated with the motor commands necessary for speech production and is found only in the cerebral hemisphere responsible for language, which is the left side in approximately 95 percent of the population. Conversely, Wernicke's area, tied to language comprehension, is found in the left temporal lobe.
