Correct Response: B. The comprehensible input hypothesis asserts that language learners learn best when language input is just beyond the level of language they have achieved. This ensures that students do not feel overwhelmed but instead are challenged just enough to advance. A is incorrect because using a familiar aural selection appropriate for emerging-level students would be too easy for students at the developing level. C is incorrect because providing a difficult aural selection for the students in this scenario may frustrate them, even if they are given a written script to which they can refer. D does not detail the difficulty level of the aural selection at all in relation to comprehensible input but instead focuses on the written translation of the selection, making it an incorrect answer as well.
