Which term means simple or unadorned in style?

• A. Plain
• B. Simple
• C. Sputnik
• D. Bludgeoning of Chance

Answer: (A)

Plain describes style that is simple or unadorned, with no extra decoration or embellishment. This makes it the best fit for a description of style that is straightforward and without ornamentation, such as plain clothing or a plain design. While simple can mean not complicated, it doesn't necessarily imply lack of decoration in the same way; plain emphasizes the absence of adornment. The other options don't match: Sputnik is a proper noun unrelated to style, and “Bludgeoning of Chance” isn’t a standard term for describing style.
