This question tests the rules of forming tag questions in English grammar. A tag question consists of a statement followed by a short question that confirms or checks the information. The key rule is that if the main clause is negative, the tag must be positive, and vice versa. In this sentence, 'You can't hear the chirping of the birds from outside' is a negative statement using the modal verb 'can'. Therefore, the tag question must use the positive form of the same auxiliary/modal verb. Since 'can't' is negative, we need 'can' in positive form. Additionally, the subject of the main clause is 'you', so the pronoun in the tag should also be 'you'. Option C (can you) correctly follows this pattern: positive modal + matching subject pronoun. Option A and D are incorrect because they use 'were/was' which doesn't match the modal verb 'can'. Option B is wrong because it uses 'she' instead of matching the subject 'you'. Key Points: - Negative statement requires positive tag question. - Use the same auxiliary/modal verb from the main clause. - Match the subject pronoun in the tag to the main clause.
