Which Statement Accurately Describes the Relationship Between Synaptic Pruning and the Prefrontal

Which statement accurately describes the relationship between synaptic pruning and the prefrontal cortex in adolescence?

A) Synaptic pruning occurs at an accelerated rate decreasing the unused synapses therefore thinning and molding the prefrontal cortex
B) Synaptic pruning increases the unmyelinated brain matter adding and molding the prefrontal cortex.
C) Myelinated brain matter is increased by synaptic pruning which then increases the speed of thought and decision-making in the prefrontal cortex.
D) Synaptic pruning decreases so that the molding of the prefrontal cortex may increase in unmyelinated neurons.
