Arrange the stages of Piaget's theory of cognitive development in ascending order?

A) operational stage

B) Pre-operational stage.

C) Sensorimotor stage

D) Formal operation stage

Choose correct answer from the options given below:

The correct answer is C, B, A, D.

Jean Piaget proposed a comprehensive theory about the nature and development of human intelligence, detailing four distinct stages of cognitive development. To arrange these stages in ascending order (from birth through adulthood), we look at the chronological order in which they occur:
1. Sensorimotor stage (C): This stage lasts from birth to approximately 2 years of age. During this period, infants construct an understanding of the world by coordinating sensory experiences with physical, motoric actions.
2. Pre-operational stage (B): This stage spans from about 2 to 7 years of age. Children start to represent the world with words, images, and drawings, showing an increase in symbolic thinking, though logical reasoning is not yet present.
3. Concrete Operational stage (A): This stage occurs from roughly 7 to 11 years of age. Children begin to think logically about concrete events and understand the concept of conservation.
4. Formal Operational stage (D): This final stage begins around age 11 or 12 and extends into adulthood. Individuals move beyond concrete experiences and begin to think in abstract and more logical ways.

Therefore, the ascending chronological order of the stages is Sensorimotor (C) ⇒ Pre-operational (B) ⇒ Concrete Operational (A) ⇒ Formal Operational (D), which corresponds to the sequence C, B, A, D.
