B. This citation is correct, an author's name is introduced, and the page number is given after the direct quotation.
Explanation:
In the Modern Language Association style of referencing, parenthetical citation is usually required when a writer refers to a literary work that is not his. The authors last name and the page number where the idea is gotten are included in the in-text citation.
If the author's name has been introduced before and now used in a sentence, just the page number could suffice in the in-text citation. This is same as what was obtainable in the excerpt above. The author's last name was used in the same sentence because it had already been introduced. Therefore, the page number where the direct quotation was obtained could suffice in the in-text citation.
Romeo is not greedy, but he is definitely young and passionate - especially for Juliet. He is also quite fickle because he changed his mind a lot and his feelings vary throughout the play.
