Correct Answer:
C. Museum
Explanation:
The correct answer is Museum because the Louvre is the world's largest and most visited art museum.
- Step 1 (Location and Fame): Located in Paris, France, the Louvre houses tens of thousands of historic art pieces, including the famous Mona Lisa and the Venus de Milo.
- Step 2 (The Landmark): While the building itself was originally built as a royal palace fortress, it is globally celebrated today strictly as a national art institution and museum.
- Incorrect Options:
- Mountain and River are incorrect because the Louvre is a man-made structure, not a natural geographical feature.
- Palace is a common trap; though it was a palace in the past, its primary official designation today is a museum.
