If a guitar string has a fundamental frequency of 500 hz, which one of the following frequencies can set the string into resonant vibration?

I had to look for the options and here is my

Given that a guitar string has a basic frequency of 500hz, the frequency that can be set for this into resonant vibration would be 1500 Hz. The resonant vibration here is necessary in musical instruments because it delivers a vibrating system which leads to a higher amplitude at a particular frequency.
