Concept:Vygotsky’s sociocultural theory states that children actively build knowledge through social interactions, especially with the help of more knowledgeable adults or peers.Explanation:Children do not passively receive information. They construct their own understanding during collaborative activities. The zone of proximal development (ZPD) is the gap between what a child can do alone and what they can achieve with guidance. Learning happens inside the ZPD when adults provide scaffolded support. Thus, children develop by actively engaging with support from others.Answer:Option B: Children construct their own understanding with support from adults.
