Option 1 : Stage-Formal operational; Characteristic-Hypo-thetico deductive reasoning 

Cognitive Development Theory- Jean Piaget said that a child's power to reflect and discover the reality of life not only depends on the child's maturity level or on his or her experience but on the interaction of both.

 Jean Piaget made a systematic study of cognitive development among children of different age groups and he categorized it into different developmental stages. These stages are-

  • Sensory-motor stage (0 to 2 years),
  • Pre-operational stage (2 to 6 years),
  • Concrete operational stage (6 to 11 years), and 
  • Formal Operational stage (11+ years to adolescence).

Formal Operational Stage- According to Jean Piaget, this is a stage for a child who belongs from the age group of 11 years till adolescence. Changes are as-

  • Hypothetical- deductive logic begins.
  • Divergent/Convergent thinking.
  • Creative thinking.

Thus we can conclude that the ability of Hypo-thetico deductive reasoning comes in the formal operational stage of Jean Piaget's cognitive development theory.
