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 C.
Option A is incorrect because quotation marks in a sentence begin when the direct speech begins and end when the direct speech ends.
Option B is incorrect as, the speech is not enclosed within quotation marks.
Option D is incorrect because the punctuations are not included within the quoted text.
