Mark, who is 14 years old, notices that recently he has become much clumsier. One reason the text suggests for this clumsiness is that the adolescent growth spurt is often accompanied by:
A) asymmetrical growth in legs, feet, arms, and hands
B) excess body fat is being deposited in the breasts, which will later disappear
C) a short-term reduction in the size of the motor cortex in the brain
D) the overproduction of red blood cells that provide excess energy in the muscles
