Answer:
B.
Step-by-step explanation:
Modern Language Association (or MLA) in-text citation is the format style used in literary works or any humanities studies to cite the sources referred for the study.
The correct format for citing any source is to mention page no(s) in parentheses, mention the name of the author of whose work you are paraphrasing. The name of the author can appear either in the sentence, if not then it should be compulsorily mentioned in parentheses with page no(s).
Option A and C are incorrect since in the first one, author's name is not cited, and in the later, page no(s) is missing. In Option D, author's name is mentioned both in the sentence and in parentheses, so, making it incorrect use of MLA citation.
Hence, The correct MLA in-text citation is used in option B.
