According to Jean Piaget, which developmental stage occurs from ages 7 to 11?

The correct choice is the Concrete Operational stage, which according to Jean Piaget, occurs in children approximately between the ages of 7 and 11 years. During this developmental period, children begin to think logically about concrete events. They gain a better understanding of the concepts of time, space, and quantity, which allows them to perform operations on objects in a logical manner.

This stage is characterized by the ability to classify objects and understand the concept of conservation, meaning that a child recognizes that the quantity of a substance doesn't change even if its shape or appearance does. For example, a child in the concrete operational stage understands that pouring liquid from a tall, thin container into a short, wide container does not change the amount of liquid.

The other stages, such as Pre-operational, Formal Operational, and Sensorimotor, represent different periods of cognitive development. The Pre-operational stage, which occurs before the Concrete Operational stage (around ages 2 to 7), is marked by symbolic thinking and egocentric perspectives. The Formal Operational stage follows the Concrete Operational stage (typically beginning around age 12) and is characterized by the ability to think abstractly and systematically. The Sensorimotor stage occurs even earlier, from birth to about age
