Play involves the repetition of behavior when new skills are being learned or when physical or mental mastery and coordination of skills are required for games or sports.

The correct answer is: Practice play.

Explanation:

Practice play is a concept proposed by Psychologist Jean Piaget that can be understood as the repetition by the individual of certain behavioral patterns such as shaking, making movements with their fingers, making sounds and so on, that are necessary or required for other games.

It is a form of practice because these are movements that are necessary for performing other games and sports, and the infant repeats them to get familiar with them.

In conclusion, the correct answer is "Practice play".
