Correct option is B
The correct answer is Direct method. The Direct Method, also known as the Natural Method, is characterized by the exclusive use of the target language in the classroom, effectively eliminating the use of the learner's native language. This method aims to mimic natural language acquisition in children, who learn their native language through immersive exposure without translation. This approach contrasts with others like the Communicative Approach or the Audio-lingual Method, which may incorporate the native language for clarity, explanations, or comparison during the learning process.
