The correct answer is **Option C: Length**.
Vocal cords (or vocal folds) that are longer tend to produce lower frequencies when they vibrate. This is because the length and mass of the vocal cords affect their rate of vibration. Longer and thicker vocal cords generally vibrate more slowly, producing lower pitches, while shorter and thinner vocal cords vibrate more quickly, producing higher pitches.
