The parenthetical citation in option A is correct. William Shakespeare's original Globe Theatre was built in 1599 (Ferguson 25).
When you add a direct quotation into a sentence, you must cite the source. Fit quotations within your sentences, making sure the sentences are grammatically correct.
An example is:
“quotations are effective in research papers when used selectively” (Gibaldi 109).
Generally, researchers incorporate brief parenthetical citations in their writing in order to acknowledge references to other people's work.
Choice B is the correct option, in the current MLA format, you finish the quote then add your citation. You do not need a comma to separate the author and page number. Author first, then page number<span />
