Lev Vygotsky believed that development :

The correct option is results directly from social interaction.

Explanation:

Lev Vygotsky's Sociocultural Theory of Cognitive Development emphasizes the fundamental role of social interaction in the development of cognition. According to Vygotsky, learning is a social process where cognitive development results directly from interactions with more knowledgeable others (such as parents, teachers, and peers) and cultural tools within a child's environment (the Zone of Proximal Development).

Unlike theorists like Jean Piaget, who viewed development as occurring in discrete stages or unfolding primarily through individual maturation, Vygotsky believed that continuous learning occurs through social collaboration and language prior to being internalized by the individual.
