Read these lines: "Boots which extended halfway up his calves, and which were trimmed at the tops with rich brown fur, completed the impression of barbaric opulence which was suggested by his whole appearance." As used in the quoted lines, "opulence" most nearly means

1. The word sits at the end of a run of costly details: tall boots, rich brown fur trim. 2. Those details are expensive rather than plain, so the word must point towards wealth. 3. The wealth is called barbaric, which marks it as loud rather than restrained. 4. So opulence here means a showy display of great wealth, option C. 5. Quiet good taste is the trap, because it also concerns dress but pulls in the opposite direction. 6. Threadbare clothing contradicts the fur and the tall boots outright. 7. Strength built by hard work describes a body rather than what a person is wearing. _Source: Arthur Conan Doyle, The Adventures of Sherlock Holmes (1892), A Scandal in Bohemia_
