A. 10 Hz to 80 Hz
B. 50 Hz to 80 Hz
C. 50Hz to 15000 Hz
D. 15000 Hz and above
✅ The correct answer is option C.
The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours. Here, option C is correct.
