Solution:The correct sequence of the language areas of the human brain in the order in which they involve in hearing, understanding and saying a word is-
Posterior speech cortex → Arcuate Fasciculus→ Anterior speech cortex → Motor cortex.
Posterior speech cortex: Wernicke area, region of the brain that contains motor neurons involved in the comprehension of speech.
Arcuate fasciculus: Its key function is to connect Broca's and Wernick's areas, which are involved in producing and understanding language. Anterior speech cortex: Broca's area, or the Broca area is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain with function linked to speech production.
Motor cortex: The motor cortex is the region of the cerebral cortex involved in the planning, controling and execution of voluntary movements.
Thus, option (d) is appropriate answer.
