In Piaget's concrete operational stage, which ability becomes possible for the child?

• A. Abstract reasoning only
• B. Egocentric thoughts
• C. Perform mental operations
• D. Reason about possibilities

Answer: (C)

In Piaget's concrete operational stage, the essential development is the ability to perform mental operations on concrete objects and events. Mental operations are internal, reversible steps that let a child reason logically about concrete situations without having to act everything out physically. For example, a child can conserve liquid: they understand that pouring water from a tall, thin glass into a short, wide one doesn’t change the amount, even though it changes appearance, and they can work through related tasks in their head. This internal manipulation—reversibility, decomposing problems, and applying logical rules to tangible items—distinguishes concrete operational thinking from earlier stages. That’s why this option best fits what becomes possible. By contrast, abstract or hypothetical reasoning and shifting perspectives without concrete cues are more characteristic of later stages, while egocentrism is more typical of earlier development.
