Under Lev Vygotsky's Socio-Cultural Theory, analyzing the concepts of 'Zone of Proximal Development' (ZPD) and 'Scaffolding', if a learner is unable to perform a complex cognitive task independently, but successfully completes it with immediate, structured, and temporary guidance from a competent adult or More Knowledgeable Other (MKO), which of the following statements is most authentic and scientifically true regarding this theoretical paradigm of Vygotsky?

According to Lev Vygotsky's socio-cultural theory, development is a socially mediated process. The 'Zone of Proximal Development' (ZPD) is the distance between the actual developmental level (determined by independent problem solving) and the higher potential developmental level (achieved under adult guidance or collaboration with capable peers, i.e., MKO). 'Scaffolding' is the temporary and flexible support provided during this process, which is gradually removed as the learner's capability increases.
