Answer:
The sentence that shows the correct placement of punctuation is the following one: "Perhaps," Phil suggested, "we should postpone the party." (D)
Explanation:
Quotation marks are used when you want to include someone else's words in your writing. In American English, commas and periods always go inside the quotation marks ("perhaps,"). What is more, if you are splitting the quote in half to introduce a parenthetical, you should not capitalize the second part of the quote. The parenthetical should not be included inside the quotation because it is not something said by someone else (B). Because of these reasons, D is the correct answer.
