Identify the part which contains the error.
Unfortunately, (a) I can’t (b) hear properly, (c) is it? (d)

Correct option is D

Option (d) contains an error.
Detailed Explanation (English):
• The sentence is negative: “I can’t hear properly”.
• In question tags, we use:
– negative statement + positive tag
– and the tag must use the same auxiliary/modal as the statement.
• The auxiliary/modal here is can (can’t).
• So the correct tag should be: “can I?”
• “is it?” is wrong because it uses is (be-verb), which does not match the main clause.
Correct sentence: Unfortunately, I can’t hear properly, can I?
Grammatical Rule Used (English):
• Tag question rule: Use the same auxiliary/modal from the statement.
• Negative statement → positive tag.
• can’t → can + subject (I) → “can I?”
Grammatical Rule Used (Hindi):
• Question tag में main sentence का same helping verb/modal ही आता है।
• Negative sentence के साथ positive tag आता है।
• “I can’t …” में modal can है, इसलिए tag होगा: can I?
• “is it?” गलत है क्योंकि यह “be-verb” का tag है और sentence से match नहीं करता।
Example:
• He isn’t coming, is he?
• You can swim, can’t you?
