One element replaces another element in a compound.
Explanation: A single-displacement reaction has the form A + BC → AC + B (or D + BC → BD + C), where a more reactive element displaces a less reactive element from a compound. The other choices are incorrect: switching elements between two compounds describes double-displacement; a precipitate or oxygen is not required for a single-displacement reaction.
