Young teens are not fully equipped for curbing risky behavior or making long-term plans because of the incomplete maturation of their: A) thalamus.
B) cerebellum.
C) frontal lobes.
D) somatosensory cortex.

C) frontal lobes

Explanation:

"The frontal lobe plays a key role in future planning, including self-management and decision-making.

People with frontal lobe damage often struggle with gathering information, remembering previous experiences, and making decisions based on this input.

Some of the many other functions the frontal lobe plays in daily functions include:

Speech and language production: Broca’s area, a region in the frontal lobe, helps put thoughts into words. Damage to this area can undermine the ability to speak, to understand language, or to produce speech that makes sense.

Some motor skills: The frontal lobe houses the primary motor cortex, which helps coordinate voluntary movements, including walking and running.

Comparing objects: The frontal lobe helps categorize and classify objects, in addition to distinguishing one item from another.

Forming memories: Virtually every brain region plays a role in memory, so the frontal lobe is not unique. However, research suggests it plays a key role in forming long-term memories.

Understanding and reacting to the feelings of others: The frontal lobe is vital for empathy.

Forming personality: The complex interplay of impulse control, memory, and other tasks helps form a person’s key characteristics. Damage to the frontal lobe can radically alter personality.

Reward-seeking behavior and motivation: Most of the brain’s dopamine-sensitive neurons are in the frontal lobe. Dopamine is a brain chemical that helps support feelings of reward and motivation.

Managing attention, including selective attention: When the frontal lobe cannot properly manage attention, then conditions, such as attention deficit disorder (ADHD), may develop."
