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.
