Final answer:
The frontal lobe is primarily involved in regulating emotions, executive functions such as working memory and decision-making, and controlling movement, rather than processing sensory information like sight or sound.
Step-by-step explanation:
Functions of the Frontal Lobe
The frontal lobe, located at the front of the brain, is associated with a variety of functions. One of its roles includes regulating emotions as part of its involvement in personality, socialization, and assessing risk. It also contains the motor cortex which is vital for planning and coordinating movement, and the prefrontal cortex which is key for executive functions such as working memory and decision-making. Additionally, Broca's area within the frontal lobe is essential for language production. Contrary to the functions of the other lobes, the frontal lobe is not typically involved in sensory processing like visual information, which is the domain of the occipital lobe, or auditory perception, which is handled by the temporal lobe.
Therefore, in terms of the choices given in the question, the frontal lobe is involved in b) regulating emotions.
