Question

when should you not capitalize prepositions in a title?

• when they have five or more letters
• when they are the first word of the title
• when they have three or less letters
• when they are the last word of the title

Explanation:

In title capitalization rules (e.g., in English language conventions for titles like in MLA, APA, or general style guides), prepositions are typically not capitalized when they have three or fewer letters (e.g., "of", "in", "on", "at"). The other options are incorrect: prepositions with five or more letters may or may not be capitalized depending on style, but the "three or less" rule is a common guideline. Prepositions as the first or last word of a title are often capitalized (e.g., "In the Woods" – "In" is capitalized as the first word; "The Book of" – "of" is not capitalized because it's a short preposition, not because it's last).

Answer:

C. When they have three or less letters
