Choose the correct option from the given alternatives to write the subject for a complaint letter to the Police Commissioner complaining about the loss of a suitcase.
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Complaint regarding loss of suitcase
The subject line of a formal letter states the purpose of the letter in a short, formal phrase, usually a noun phrase without a full sentence. "Complaint regarding loss of suitcase" tells the Police Commissioner at once what the letter is about.
Example: Subject: Complaint regarding irregular water supply.
Why the Other Options are Incorrect?
Option 1: Suitcase is lost somewhere — Incorrect. It is a vague sentence, not a subject line, and does not say it is a complaint.
Option 2: Lost suitcase please find it — Incorrect. It is an informal request, unsuitable for a letter to a senior officer.
Option 4: Grieving for lost suitcase — Incorrect. It expresses personal feeling; a subject line states the matter, not the writer's emotions.
