Which of the following describes cognitive tasks typical of the concrete operational stage?

• A. Abstract reasoning with hypothetical ideas
• B. Logic applied and objective interpretations
• C. Reliance on magical thinking
• D. Sensorimotor exploration

Answer: (B)

In concrete operational thinking, children use logic with real, tangible problems and objects. They can perform mental operations on concrete actions, understand that certain properties stay the same even when appearance changes (conservation), and see that actions can be reversed (reversibility). They also categorize, order, and reason about concrete situations using objective observations. This description fits best: logic applied and objective interpretations, because it captures how they reason logically about concrete materials and events rather than dealing with abstract ideas.

Abstract reasoning with hypothetical ideas happens later, in the formal operational stage. Magical thinking is characteristic of the earlier preoperational stage, and sensorimotor exploration belongs to the infancy and toddler years, before these logical skills develop.
