Answer & Solution
Correct answer: A. Young child
Vocal cord length determines voice frequency: shorter cords vibrate faster. Men's vocal cords ≈ 20 mm, women's ≈ 15 mm, children's are even shorter — so children's voices are typically the highest in pitch. (Among adults alone, women's voices are generally higher than men's.)
