Step by step solution

01

Understand the functions of each brain area

The student must know the functions of each part of the brain: -A. Hypothalamus: Controls body temperature, hunger, sleep, and other homeostatic systems. -B. Corpus Callosum: Connects the two hemispheres of the brain, allowing for communication between them. -C. Prefrontal Cortex: Responsible for complex cognitive behavior, decision-making, and moderating social behavior. -D. Occipital Lobe: Mainly responsible for visual processing.
02

Determine the development timeline of each brain area

The student must understand when each part of the brain develops: -A. Hypothalamus: Develops relatively early in life to help regulate basic bodily functions. -B. Corpus Callosum: Develops throughout childhood and adolescence, but is not the last area to mature. -C. Prefrontal Cortex: Develops continuously through childhood, adolescence, and into early adulthood, maturing last. -D. Occipital Lobe: Develops earlier in life as a more primary area of the brain, focused on visual processing.
03

Identify the last area of the brain to mature

Based on the development timeline and functions of each brain area, the last area to mature fully is the prefrontal cortex (C). Therefore, the correct answer to this question is the prefrontal cortex.
