Which concept describes that properties such as volume, area, and number remain the same despite changes in the arrangement of objects?

• A. Volume remains constant even when shape changes
• B. Egocentrism
• C. Object Permanence
• D. Conservation

Answer: (D)

This question is about conservation—the idea that certain properties stay the same even when the arrangement of objects changes. In other words, volume, area, or number remains constant despite rearranging, clustering, or reshaping the visible setup. This means you can pour liquid into a differently shaped container and the amount is still the same; you can spread coins out or stack them, and the total number doesn’t change. The concept shows that quantity is not just about how things look, but about the underlying amount. Other ideas describe different cognitive skills. Egocentrism is about not being able to see things from someone else’s point of view, and object permanence is understanding that objects continue to exist even when they aren’t seen. The option mentioning volume in a single shape-change scenario hints at a specific case, but the broader principle that applies to volume, area, and number across rearrangements is conservation.
