The statement that is TRUE about the frontal lobes of the brain is:

They are responsible for impulse control.

The frontal lobes play a crucial role in executive functions including decision-making, reasoning, problem-solving, and impulse control.

The other statements have issues:

  • They are responsible for taste and smell: This function is primarily associated with the parietal and temporal lobes, specifically the gustatory and olfactory areas.

  • They are the first lobes to fully mature: The frontal lobes are among the last areas of the brain to mature, often not fully developing until a person's mid-20s.

  • They are fully developed in middle adolescence: This is inaccurate, as the frontal lobes continue to develop well into young adulthood.
