Answer: (D)

Verified step by step guidance

1. Identify the stages of cognitive development according to Piaget's theory: Sensorimotor, Preoperational, Concrete Operational, and Formal Operational.
2. Understand the age ranges associated with each stage: Sensorimotor (birth to 2 years), Preoperational (2 to 7 years), Concrete Operational (7 to 11 years), and Formal Operational (12 years and up).
3. Recognize that middle and late childhood typically correspond to the Concrete Operational stage, which involves ages 7 to 11 years.
4. Recall the key cognitive milestones of the Concrete Operational stage, such as the development of logical thinking about concrete events and understanding conservation (the idea that quantity remains the same despite changes in shape or appearance).
5. Compare the given options to these milestones and determine that the milestone most commonly achieved during middle and late childhood is the ability to think logically about concrete events and understand conservation.
