According to Piaget's Theory of Cognitive Development, children learn by:

Piaget's Theory of Cognitive Development emphasizes that children learn through active exploration and interaction with their environment, which leads them to construct knowledge based on their experiences. According to Piaget, cognitive development occurs through a series of stages where children build upon their existing knowledge by assimilating new experiences and accommodating their understandings when faced with information that cannot be integrated into their existing framework. This process of building upon knowledge is crucial as it allows children to develop more complex thinking and reasoning skills over time.

In essence, Piaget believed that children are not passive recipients of information but rather active learners who engage with their surroundings and make sense of the world through their unique experiences. This idea supports the notion that knowledge is constructed rather than memorized or learned solely through imitation. Thus, option C aligns perfectly with Piaget's viewpoint, highlighting the importance of experiential learning in cognitive development.
