The statement that is TRUE about the frontal lobes of the brain is:
They are responsible for impulse control.
The frontal lobes are involved in various functions, including executive functions, decision-making, problem-solving, and impulse control. They do not primarily manage taste and smell (those functions are more associated with the parietal and temporal lobes) and they are not fully developed until later in young adulthood, rather than in middle adolescence.
