According to Piaget's theory of cognitive development, children between the ages of 7 and 12 are in the concrete operational stage. Nada, who is able to think logically and come up with a hypothesis to test, is likely in this stage. Hakim, who is confused and doesn't understand this approach, is likely in the preoperational stage, which is the stage for children between the ages of 2 and 7. Therefore, the best option is B (concrete operational; preoperational).
