Which sentence demonstrates correct capitalization of multiple proper nouns in a list?

• A. I visited paris, france, and italy last summer.
• B. I visited Paris, France, and Italy last summer.
• C. I visited Paris, france, and Italy last summer.
• D. I visited Paris, France and Italy last summer.

Answer: (B)

Capitalizing proper nouns in a list and separating items with appropriate punctuation is the key idea here. Paris, France, and Italy are all specific names, so each word that is a proper noun needs a capital letter. The sentence that shows this correctly also uses the serial comma before “and,” which helps prevent misreading of the three items as one thing and keeps the list clear. So Paris, France, and Italy last summer appropriately capitalizes each proper noun and uses the comma before the final conjunction.

The other sentences fail because the proper nouns aren’t capitalized consistently (paris and france are lowercase in the first and third options), or they omit the comma before the final conjunction (which can affect readability and is the convention used in this context).
