What becomes increasingly critical as children grow older and acquire specialized motor skills

A)  experience 
B)  nutrition 
C)  genetic predisposition 
D)  maturation

As children grow older and acquire specialized motor skills, experience becomes increasingly critical. They need to practice their motor skills to improve and refine them. Without practice and experience, they may not be able to perform these skills effectively. While nutrition and genetic predisposition can affect a child's development, they are not as critical for acquiring specialized motor skills as experience. Maturation is also important, but it mainly refers to the natural process of physical and psychological development, which may not directly affect children's motor skill development.
