In this stage within Piaget's cognitive development, children begin to think logically on a concrete level, begin to develop the capacity to think from other points of view, and the child develops the ability to conceptualize in terms of reversibility.

The Concrete Operational Stage is indeed the correct answer because it accurately describes a significant phase in Piaget's theory of cognitive development, typically occurring between the ages of 7 and 11 years. During this stage, children start to utilize logical thinking about concrete events. They develop the ability to understand the concept of conservation—recognizing that quantity or value remains the same even when its appearance changes. Furthermore, children in this stage can think logically about physical objects and events and begin to understand others' perspectives, enabling them to engage in more complex social interactions and problem-solving.

The aspects of reversibility—where a child understands that actions can be reversed, leading to the original state—are pivotal during this stage, allowing them to grasp concepts like addition and subtraction in more sophisticated ways than before. This foundational stage sets the groundwork for subsequent stages of cognitive growth.

The other stages mentioned do not encompass these developments. The Sensorimotor Stage focuses primarily on sensory experiences and motor actions and does not yet involve logical reasoning. The Preoperational Stage is defined by symbolic thinking but is characterized by egocentrism and a lack of logical operations concerning concrete objects. The Formal Operational Stage follows Concrete Operational and involves abstract reasoning and problem-solving, beyond the concrete thinking characteristic of
