According to Piaget's theory, which stage comes after birth to age 2?

In Piaget's theory of cognitive development, the stage that follows the sensorimotor stage, which lasts from birth to approximately age 2, is known as the preoperational stage. This stage typically encompasses the ages of about 2 to 6 years. During the preoperational stage, children begin to engage in symbolic play and develop language skills but are not yet capable of logical reasoning. They also tend to be egocentric, viewing the world primarily from their own perspective.

This understanding of cognitive stages supports why the interval extending from 2 to 6 years fits as the correct answer, as it reflects the next phase of cognitive development in Piaget's framework. The other time frames provided don’t correctly correspond to the stages as outlined by Piaget, as they either include wider age ranges or reference the stages that follow the preoperational stage.
