Correct option is B
Lev Vygotsky’s educational theory emphasizes reciprocal teaching and collaborative learning. Reciprocal teaching is an instructional approach where students and teachers engage in dialogue, with students gradually taking on the teacher’s role. This approach helps develop critical thinking, comprehension, and problem-solving skills. It aligns with Vygotsky's principles of the Zone of Proximal Development (ZPD) and social constructivism, where learning is mediated through social interactions and collaboration.
