In the context of Child Development and Pedagogy, which of the following relationships between the concepts of 'Zone of Proximal Development' (ZPD) and 'Scaffolding' in Lev Vygotsky's socio-cultural theory is most accurate and logically correct?

In Lev Vygotsky's socio-cultural theory, the 'Zone of Proximal Development' (ZPD) represents the gap between a child's ability to solve problems independently and their ability to solve them under the guidance of an adult or a More Knowledgeable Other (MKO). 'Scaffolding' is the temporary, dynamic, and supportive framework provided by the MKO within the ZPD, which is gradually removed as the child becomes proficient in the skill. Therefore, option B most accurately defines this relationship.
