According to Lev Vygotsky's 'Socio-Cultural Theory', which of the following psychological statements is most authentic and scientifically valid regarding the concepts of 'Zone of Proximal Development' (ZPD) and 'Scaffolding', along with their practical applications in classroom teaching?

Understanding Vygotsky's ZPD and Scaffolding

According to Lev Vygotsky's Socio-Cultural Theory, the Zone of Proximal Development (ZPD) defines the gap between a learner's actual developmental level (what they can do independently) and their potential developmental level (what they can achieve under the guidance of an adult or a More Knowledgeable Other - MKO).

• ZPD: Represents the dynamic region where learning takes place through targeted assistance.
• Scaffolding: Refers to the temporary, flexible support provided by a teacher or capable peer, which is gradually faded out as the learner becomes independent.

Option B accurately captures both theoretical definitions and their practical application in educational psychology.
