Your answer would be: A) O Brussels Sprouts
"Brussels sprouts" should be capitalized as it is the name of a specific vegetable.
Capitalizing the First Word of a Sentence: The first word of every sentence should always be capitalized.
Proper Nouns: Capitalize proper nouns, which are the names of specific people, places, things, or titles. For example, "William Shakespeare," "London," and "Romeo and Juliet."
Titles and Headings: Capitalize the first and last words in titles and headings, as well as all major words in between. Articles (a, an, the), coordinating conjunctions (and, but, for, or, nor), and prepositions (in, on, of, at) are usually not capitalized unless they are the first or last word of the title.
The Pronoun "I": Always capitalize the pronoun "I" regardless of its position in a sentence.
Days, Months, and Holidays: Capitalize the names of days of the week, months, and holidays. For example, "Monday," "October," and "Christmas."
Important Historical Events: Capitalize the names of significant historical events, such as "World War II" or "the Renaissance."
Book Titles: Capitalize the first letter of each major word in a book title or the title of a literary work, including nouns, pronouns, verbs, adjectives, and adverbs. Minor words like articles, conjunctions, and prepositions are typically not capitalized unless they are the first word of the title.
Quotes in Dialogue: When writing dialogue, the first word of the quoted material should be capitalized. For example, "He said, 'I love literature.'"
These are some general capitalization rules in English literature. Keep in mind that specific style guides, such as the Chicago Manual of Style or the MLA Handbook, may have variations and additional rules for capitalization in literature.
