Which of the following is a content word?

• A. Mountain
• B. And
• C. The
• D. Is

Answer: (A)

The main idea here is distinguishing content words from function words. Mountain is a content word because it’s a noun that names a specific thing and carries concrete meaning you can picture. The other three are function words: and is a conjunction that links ideas, the is an article that marks definiteness, and is a form of the verb to be used to link or help form sentences without adding specific content on its own. In a simple sentence, content words provide the main meaning, while function words support grammar. That’s why Mountain is the correct choice.
