The restaurant is famous ______ its seafood.

• A. to
• B. by
• C. for
• D. with

Answer: (C)

This item tests the common collocation that follows the adjective famous: you’re famous for something, meaning that thing is the reason you’re well known. Here, the restaurant is well known specifically because of its seafood, so the natural and correct phrasing is famous for its seafood.

Other prepositions don’t fit the natural meaning. to isn’t used to express the reason something is known, by would imply who did the notable act or some agent, and with would suggest accompaniment rather than the cause of fame. The standard, idiomatic choice to show the reason for fame is for.
