When using direct quotations in your writing, which of the following should be placed outside the set of quotation marks?
a. question mark
b. semicolon
c. period
d. comma

Comma C because Period would mean your cutting off the sentence and semicolon is just obviously not right... and question mark.. would mean your asking a question and that would be inside of the quotation mark.

All of the above
a
b
c
d
