Which of the following is not one of the criticisms of Piaget’s theory of cognitive development?

Piaget's theory of cognitive development, while foundational, has faced several criticisms. Options A, B, and C represent valid critiques. Option A highlights that Piaget's experimental tasks might have been too complex, leading him to underestimate children's cognitive abilities, as later research with simplified tasks demonstrated earlier mastery of concepts like object permanence. Option B points to the theory's limited consideration of cultural and social factors, which are now recognized as profoundly influencing cognitive development, a perspective championed by Vygotsky. Option C notes that Piaget's stage theory provides a general framework but struggles to account for individual differences in developmental pace or style. In contrast, option D, "Evidence for the theory is based on children’s answers to questions," describes Piaget's primary methodology—his clinical interviews and observations—rather than a criticism of the theory's conceptual framework. While the interpretation of these answers can be debated, the reliance on children's verbal responses and actions was central to his groundbreaking approach to understanding cognitive processes.
