Triplen harmonics are harmonics divisible by which number?

Explanation:
Triplen harmonics are defined by their order being a multiple of three. That means the harmonic frequencies you get are 3 times the fundamental, then 9 times, 15 times, and so on. Since each of these indices is divisible by three, they are harmonics divisible by three. This is what sets them apart from harmonics tied to divisibility by other numbers. The other options don’t define triplen harmonics as their hallmark, because triplen aren’t characterized by divisibility by 2, 4, or 5.
