According to Piaget's theory, which stage of cognitive development is characterized by children beginning to think logically about concrete events?

Cognitive development involves the transition from purely sensory experiences to abstract reasoning. Knowledge of Piaget's stages is applied here to identify the specific period where children overcome egocentrism and begin utilizing inductive logic to solve concrete, physical problems. Choice A rationale The preoperational stage, occurring from ages two to seven, is marked by symbolic thought and egocentrism. Children in this stage cannot yet perform mental operations or think logically about the physical properties of objects or events. Choice B rationale The formal operational stage begins in adolescence and involves abstract thinking and hypothetical-deductive reasoning. Logic is applied to unseen possibilities and complex ideological concepts, going beyond the concrete events described in the specific question scenario. Choice C rationale The sensorimotor stage occurs from birth to age two and focuses on coordinating sensory experiences with physical motor actions. Logical thought has not yet developed, as the infant is primarily learning about object permanence and basic causality. Choice D rationale The concrete operational stage, from ages seven to eleven, is when children develop the ability to think logically about tangible objects and visible events. They understand conservation, reversibility, and can categorize items based on physical, concrete characteristics.
