Which word means three times as much, used as an adjective?

• A. Triple
• B. Quadruple
• C. Threefold
• D. Tri-fold

Answer: (C)

Think of expressing a multiplier of three with one adjective. Threefold literally means three times as much and is used to describe increases or amounts, such as a threefold increase or threefold greater. It’s common in formal or written contexts and directly conveys the idea of three times the size or amount. The other options don’t fit this exact sense as cleanly: quadruple means four times; tri-fold refers to something with three folds (like a brochure) rather than a quantity; triple can describe three parts or be a verb (to triple the amount), but threefold is the most precise and idiomatic way to say three times as much.
