Which capacity improves as a result of development in the prefrontal region?

• A. Language skills
• B. Planning and problem solving
• C. Physical growth
• D. Interhemispheric communication

Answer: (B)

The prefrontal region supports executive functions, which include planning and problem solving. As this area matures, a person gets better at organizing steps, selecting effective strategies, anticipating outcomes, and adjusting plans when obstacles arise. That direct link—planning sequences and solving novel problems—makes this capacity the one that improves with development in the prefrontal region. Language skills rely more on language-specific areas, physical growth is overall body development, and interhemispheric communication depends on connections like the corpus callosum rather than the prefrontal region itself.
