Answer:
The correct answer is: Placement stage.
Step-by-step explanation:
According to the development of artistic abilities in children, individuals go through different stages:
Scribble, Preschematic, Schematic and Dawning realism.
In the Scribble stage the child goes through 4 more stages contained within the scribble phase. One of those four stages is the one called placement stage.
During the placement stage, the individual is able to perform more controlled motions (Such as drawing specifically in a certain place on the paper, drawing in a certain manner, and so on) that are more sophisticated that his/her previous attempts.
In this case, Rick loves to scribble with crayons and hi smother noticed that all of his squiggles were in the bottom right corner of the pages.
This shows that Rick is in the Placement stage of children's artistic development.
