• A. Planning and decision-making
• B. Regulating heart rate and breathing
• C. Processing visual information
• D. Coordinating balance and movement

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the role of the frontal lobe in brain function. The frontal lobe is one of the four major lobes of the cerebral cortex and is primarily involved in higher cognitive functions.
2. Step 2: Identify the key functions associated with the frontal lobe, such as planning, decision-making, problem-solving, and controlling voluntary movements.
3. Step 3: Compare the options given with the known functions of the frontal lobe. For example, regulating heart rate and breathing is controlled by the brainstem, not the frontal lobe.
4. Step 4: Recognize that processing visual information is mainly the function of the occipital lobe, and coordinating balance and movement is primarily managed by the cerebellum.
5. Step 5: Conclude that the primary function of the frontal lobe among the options provided is planning and decision-making, as it aligns with the cognitive roles of this brain region.
