Concept:Stephen Krashen's Input Hypothesis says language acquisition happens when learners get input just beyond their current level.
Explanation:Comprehensible input means the language provided is slightly more advanced than the learner’s present ability.
Repeating the same input does not help; understanding the meaning is essential.
This input enables natural language acquisition, better communication, and effective text comprehension.
The learner improves by grasping the message, not by memorization.
Hence, the correct definition is input that is a little above the current level.
Answer:Option A: that language learners improve in a language when they are given language input that is slightly more advanced than their current level.
