<span>In D the period is outside the quotation mark. In B the question mark should be inside the quote. In C there is a period inside the quote, it should be a comma since the quote by itself is not a complete sentence :) </span> Good Luck.
<em><u>A. is the only correct sentence.</u></em> B. is wrong because the punctuation is in the wrong place. C. is wrong because there should be a comma after,"Why," D. is wrong because the period is outside of the quotation marks.
