One of the statements below contains a word used incorrectly. Choose the option which has the incorrect or inappropriate usage of the word.

The question is testing for word usage between **luxurious** and **luxuriant**. **Luxurious** refers to something expensive, elegant, or characterized by comfort and extravagance. Think of a five-star hotel suite with marble floors, silk curtains, and a personal butler - that's the kind of fancy, high-end comfort that makes something luxurious. **Luxuriant** describes something that grows abundantly or profusely, like thick vegetation or hair. Picture a jungle with dense, overflowing greenery, or someone with thick, flowing locks of hair - that lush, abundant quality is what makes something luxuriant. Option 1 -> Correct usage. "Luxurious lives" appropriately describes the elegant, comfortable lifestyle of princes. Option 2 -> Incorrect usage. Gold, silk, and velvet trimmings should be described as "luxurious" (expensive/elegant), not "luxuriant" (abundant/lush). Option 3 -> Correct usage. "Luxuriant tresses" properly describes thick, abundant golden hair. Option 4 -> Correct usage. "Luxurious suites" correctly describes elegant, high-end accommodations. Hence, **Option 2** is correct.
