Which of the following statements is most authentic and scientifically valid regarding the sequential development of the three Modes of Representation—Enactive, Iconic, and Symbolic—propounded under Jerome Bruner's 'Cognitive Development Theory', and the concept of 'Spiral Curriculum' in classroom teaching?

According to Jerome Bruner's theory of cognitive development, children's development passes through three stages: Enactive (through actions), Iconic (through images or pictures), and Symbolic (through language and abstract symbols). The main feature of Bruner's 'Spiral Curriculum' is that any subject can be taught repeatedly at every level of children's development, adapted to their understanding (in enactive, iconic, or symbolic forms) from simple to complex, deepening their understanding over time.
