The last part of the brain to mature is/are the:

B) dendrites.
C) synapses.
D) prefrontal cortex.

Prefrontal Cortex

A region of the frontal lobes of the brain implicated in a variety of complex behaviors, including planning, decision-making, and moderating social behavior.

Axons

Long, slender projections of nerve cells (neurons) that transmit electrical impulses away from the neuron's cell body to other neurons or muscles.

Dendrites

The branched extensions of neurons that receive electrical impulses from other nerve cells, facilitating inter-neuronal communication.
