In the context of Jean Piaget's theory of cognitive development, which of the following stages most accurately represents the development of 'Hypothetico-Deductive Reasoning' and 'Abstract Reasoning'?

Explanation

According to Jean Piaget's theory of cognitive development, the Formal Operational Stage (approximately from 11 years through adolescence and adulthood) is characterized by the full development of abstract thinking, logical reasoning, and hypothetico-deductive reasoning.

During this stage, individuals become capable of:

• Solving problems systematically using hypotheses without needing concrete or physical objects present.
• Analyzing complex conceptual problems and thinking about abstract ideas.
