Answer: Neyaili is in the Preoperational Stage.
Explanation: The Preoperational Stage is the second stage of cognitive development, which involves children between 2 and 7 years. In this stage children learn while playing, however, their logic is not fully developed since their perception differs on what they are seeing, or they struggle taking different points of view into consideration; for example, they might have the idea of holding more sand on the thin container just because it looks larger, even though there might be the same amount or even less sand in the fat container.
