Which closing phrase is generally considered less formal for business emails?

• A. Best regards
• B. Kind regards
• C. Yours sincerely
• D. Yours faithfully

Answer: (A)

Closing phrases in business emails set the tone. They vary from formal to friendly, and the choice signals how close you are to the recipient and how formal the message is. Best regards is a neutral, warm but still professional closing that works well in everyday business emails with colleagues, clients, or new contacts without implying high formality. It’s commonly used and versatile, making it feel more casual than the others listed. Kind regards is polite and slightly more formal, giving a more cautious or respectful tone. Yours sincerely is traditional in formal correspondence when you know the recipient’s name, which gives it a more official and respectful feel. Yours faithfully is the most formal option among these, typically used in very formal letters or when you don’t know the person’s name. So, for a generally less formal closing in business emails, Best regards is the best fit.
