When the Developmental Changes in Gray Matter Brain Volume Are

When the developmental changes in gray matter brain volume are plotted on a graph, the results show an inverted U-shaped pattern. This shape reflects changes in gray matter in what way?

A) The volume, thickness, and synaptic density of gray matter is high in early childhood and gradually decreases over time.
B) The volume, thickness, and synaptic density of gray matter is relatively low in early childhood and increases during adolescence.
C) The volume, thickness, and synaptic density of gray matter is relatively low in early childhood and stays at the same level throughout adolescence.
D) The volume, thickness, and synaptic density of gray matter is relatively low in early childhood, gradually increases during adolescence, then declines.
E) The volume, thickness, and synaptic density of gray matter is relatively high in early childhood, gradually increases during adolescence, then declines.
