Which term describes the ability to mentally reverse actions or operations?

• A. puberty
• B. preoperational stage
• C. classification
• D. reversibility

Answer: (D)

The main idea here is reversibility—the mental ability to undo an action or operation in your mind. This skill lets a person understand that a change can be reversed to return to the original state, even if appearances have shifted. For example, imagine pouring water into a tall glass and then pouring it back into the original container; the amount stays the same, showing the operation can be reversed. In development, reversibility is a hallmark of concrete operational thinking, which emerges around ages 7–11 and supports concepts like conservation and logical reasoning about transformations. The other terms aren’t about undoing actions: puberty relates to physical maturation, and classification is about grouping objects by shared properties. So the best description of mentally reversing actions is reversibility.
