Answer:
The answer is indeed letter A. your name should appear only in the closing and your signature.
Step-by-step explanation:
In the heading of a business letter, you should indeed offer some information in case the recipient of the letter decides to contact you back, such as your address, your e-mail, and your phone number. Your name, however, does not need to be included in the heading since it will appear in the closing, along with your signature. The closing in a business letter should be professional and considerate - sincerely, best regards, respectfully and so on. Right after it, your first and last names should be typed. Your handwritten signature is usually placed right above your typed name.
