Quotation marks are used to indicate material that is being reproduced word for word. According to general rule, commas and periods that are part of the original sentence go inside the quotation marks, even though they are not part of the original quotation. Thus, the correct answer should be Option A.
Option B is incorrect as, the punctuation that are part of the original sentence go inside the quoted text.
Option C is incorrect because all the punctuations required in the given sentence are not included in the sentence.
Option D is incorrect because the speech is not enclosed within quotation marks.
