Mohan can now think in terms of propositions and deal with propositions instead of objects. He deals with sums total of possibilities rather than empirical situations. He takes final steps towards versatility in thought. Mohan is at which stage of Piaget's model?

Correct option is C

Solution: Correct Answer: (c) Formal Operations Stage
Explanation:
At the Formal Operations Stage, the child develops the ability to think abstractly, logically, and hypothetically.
Mohan can now think in terms of propositions (ideas, theories, and possibilities) rather than only concrete objects.
He is able to reason about situations that are not directly experienced — this is the hallmark of formal operational thought.
Thus, Mohan is in Piaget’s Formal Operational Stage of cognitive development.
Information Booster:
→Jean Piaget proposed four stages of cognitive development, showing how children’s thinking evolves with age.
→The Formal Operational Stage typically begins around 11–12 years and continues into adulthood.
At this stage, individuals develop:
→Abstract thinking (thinking beyond the here and now)
→Hypothetic-deductive reasoning (testing hypotheses logically)
→Metacognition (thinking about one’s own thinking)
→Propositional thought (reasoning with statements or propositions instead of tangible objects)
Additional Knowledge:
Example: A child in the concrete stage can solve problems about real apples or blocks.
But a child in the formal operations stage can handle “If–then” statements like:
→ “If all men are mortal and Socrates is a man, then Socrates is mortal.”
Educational implication:
→Teachers can now use abstract problems, scientific reasoning, and hypothetical questions in learning since learners at this stage can think beyond direct experience.
