Which of the following is not part of a piano a damper a soundboard of mallet or a hammer

Answer 1

A soundboard is not part of a piano; it is typically associated with string instruments like guitars or violins. A damper, hammer, and mallet (if referring to a specific type of hammer used in certain pianos, like a mallet-action piano) are all components related to how a piano produces sound. In a standard piano, the hammer strikes the strings, and the damper silences them when not played.
