The reason for using a harmonic oscillator as a clock's time-keeper is so that the clock will keep accurate time even if the
A) frequency of the time-keeper's oscillation changes.
B) stiffness of the time-keeper's restoring force changes.
C) amplitude of the time-keeper's oscillation changes.
D) mass of the time-keeper's moving object changes.

The period of a harmonic oscillator, and thus its frequency, is independent of the amplitude of oscillation. This means that even if the amplitude changes, the time it takes for one complete oscillation remains the same, allowing the clock to keep accurate time.
