Why the Other Options are Incorrect?
Option 1: informal letter — Incorrect. An informal letter is written to friends and family, not to an organisation.
Option 3: complaint letter — Incorrect. A complaint letter reports a problem with a product or service and asks for it to be put right; it does not seek information.
Option 4: formal letter — Incorrect. "Formal letter" is the broad class that includes enquiry, complaint and order letters; the letter written specifically to seek information is the enquiry letter.
