Which of the following elements comes last in a business letter?

Signature

The correct answer is Option (2) - Signature

In a business letter, the signature comes last because it signifies the conclusion of the letter, following the courteous leave-taking (e.g., "Yours sincerely"). Here’s the typical structure of a business letter:

1. Date: Placed at the top of the letter.
2. Body of the letter: The main content or message of the letter.
3. Courteous leave-taking: Polite closing phrases like "Yours sincerely" or "Yours faithfully."
4. Signature: The final element, which includes the writer's handwritten name and sometimes their printed name and designation.
