Which one of the following statements about writing business letters is True?
a. If you forget one of the crucial points of your letter, provide the information in a postscript.
b. "Respectfully yours" is usually the most appropriate complimentary close for business correspondence.
c. If the professional title and gender of your recipient are unknown, the courtesy title " Mr/s." is the safest way to begin the inside address and salutation.
d. Block style gives your letter a contemporary appearance, and it is fast to key.
I believe the answer should be b, but I am torn between b and d.
Both b and d are true. Your text may have different information, though.
