Which of the following frequencies is in the audible range?

Explanation:
Audible sound for humans generally falls between about 20 Hz and 20 kHz. Frequencies outside this range aren’t heard as sound, while those inside can be heard as tones. The radio and microwave frequencies (like 100 MHz and 10,000 MHz) are far above what we can hear. A frequency of 10 Hz is below the lower end of the audible range. A frequency of 10 kHz is within 20 Hz–20 kHz, so it can be heard as a tone. Therefore, 10 kHz is in the audible range.
