Which of the following is a proper complimentary closing in a letter?

• A. Yours truly
• B. Sincerely yours
• C. Best regards
• D. Kind regards

Answer: (B)

In letter writing, the closing should match the level of formality of the message. A traditional, formal closing like “Sincerely yours” fits most professional letters because it conveys genuine respect without sounding overly stiff. It strikes a balance that keeps the tone courteous and business-appropriate. Yours truly has a slightly older, more formal flavor, and in many modern contexts it’s less common. Closings such as “Best regards” or “Kind regards” are friendly and polite, but they can feel less formal than a true professional closing, depending on the workplace culture. So, when you want a safe, universally appropriate choice for formal correspondence, “Sincerely yours” is the best fit.
