Which U.S. state is made up of an archipelago?

Hawaii is composed of an archipelago, which is a group of islands clustered together. It consists of over 130 islands, with the eight main islands including Hawai'i (the Big Island), Maui, O'ahu, and Kaua'i, among others. This unique geographical feature distinguishes Hawaii from the other options, as it is the only U.S. state that is entirely made up of a chain of islands rather than being part of the continental landmass.

In contrast, Florida is a peninsula and has both coastline and inland territory but does not consist of islands in an archipelago format. California is situated on the mainland and has coastal features, while New York, primarily known for its significant urban area, is also part of the mainland and includes no major island group that makes it an archipelago. Thus, Hawaii's status as an archipelago is what makes it the correct answer to the question regarding U.S. states made up of an archipelago.
