Answer:
A) Understanding with the help from a peer
Explanation:
The concept of the zone of proximal development was first introduced by Russian psychologist Lev Vygotsky (1896–1934). According to him, through dialogue with a more knowledgeable peer or an adult, social interaction and sense-making, a child learns how to solve certain problems and perform tasks independently. Today, this concept is usually defined as the distance between what a learner can do alone, and what they can do with the help of an adult.
