Piaget's theory of cognitive development states that children in the concrete operational stage (ages 7-11) can pass conservation tasks, meaning they understand that even if an object changes shape or position, its quantity or volume remains the same. This is a key characteristic of this developmental stage. Option A is more characteristic of the preoperational stage, while option C is a specific math rule not necessarily related to concrete operations. Option D refers to an error made by infants in the sensorimotor stage, not the concrete operational stage.
