The correct answer is:
**The person sings at the same frequency as the piano wire, called the resonance frequency.**
When a person sings at the same frequency (or a harmonic) as a vibrating string or wire, it can cause the wire to vibrate due to resonance. This phenomenon occurs because the sound waves created by the person’s voice match the natural frequency of the wire, amplifying the vibration.
