The elements of a regular business letter are: Letterhead or sender's address. Date the letter is written or sent. Inside address, the name title organization name and address. Reference line preceded by 'RE:' state the subject of the letter, Salutation. Complimentary closing. Signature <span>Typed or printed name of sender. So as you can see there is no brith date. So the answer is B. I hope this is good and if its the only answer then I hope to recieve a brainliest answer. Really appreaciate my dear</span>
