• A. It is primarily responsible for processing auditory information and language.
• B. It is involved in reasoning, planning, problem-solving, and voluntary movement.

Answer: (B)

Verified step by step guidance

1. Identify the location and general role of the frontal lobe in the brain. The frontal lobe is located at the front part of the brain and is associated with higher cognitive functions.
2. Understand the primary functions attributed to the frontal lobe, which include reasoning, planning, problem-solving, and controlling voluntary movements.
3. Compare the given options with the known functions of the frontal lobe: auditory processing is mainly linked to the temporal lobe, visual processing to the occipital lobe, and balance and coordination to the cerebellum.
4. Recognize that the option describing involvement in reasoning, planning, problem-solving, and voluntary movement aligns best with the frontal lobe's functions.
5. Conclude that the primary function of the frontal lobe is related to executive functions and motor control, making the correct choice the one that highlights these aspects.
