When addressing Mrs. Elizabeth Dunbar, what is the most appropriate way to refer to her?

Addressing Mrs. Elizabeth Dunbar as "Mrs. Dunbar" is the most appropriate choice because it respects her marital status and uses her last name, which is generally considered formal and polite in professional settings. This form of address acknowledges her as a married woman, reflecting both her personal identity and societal norms regarding titles.

Using "Miss Elizabeth" is less appropriate since "Miss" typically denotes an unmarried woman, which does not align with her marital status. Referring to her as "Ma'am" would be overly formal for personal address and lacks personalization in this context. The option of "Liz" is too informal and assumes a level of familiarity that may not exist in a professional interaction. Overall, addressing her as "Mrs. Dunbar" strikes a balance between professionalism and respect.
