The correct option is B. The generally accepted audible range of hearing for young, healthy humans is from 20 Hz to 20 kHz.

– ‘Hz’ stands for Hertz, which is a unit of frequency (cycles per second).
– ‘kHz’ stands for kilohertz, which is 1000 Hertz.
– The lower limit of human hearing is around 20 Hz, and the upper limit is around 20,000 Hz (20 kHz).

Hearing range can vary between individuals and typically decreases with age, especially at higher frequencies. Frequencies below 20 Hz are called infrasound, and frequencies above 20 kHz are called ultrasound. Humans cannot hear these sounds, although some animals can.
