Which of the following option mentions an appropriate concluding sentence to a Letter of Enquiry?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → I hope to hear from you soon
A letter of enquiry asks for information, for example about a course, a product or a service. It closes politely, showing that the writer is waiting for a reply without pressing the reader. "I hope to hear from you soon" does this and is the standard concluding sentence.
Why the Other Options are Incorrect?
Option 2: Please write a reply as soon as possible — Incorrect. It sounds impatient and demanding; the writer is asking a favour and should not hurry the reader.
Option 3: Call the concerned authority if you have any doubt — Incorrect. In a letter of enquiry it is the writer who needs information; telling the reader to call someone about a doubt makes no sense.
Option 4: Call the undersigned — Incorrect. It is an abrupt order, the language of a notice, not a polite close to a letter.
