• A. 20 - 20,000Hz
• B. 40 - 20,000Hz
• C. 60 - 20,000Hz
• D. 200 - 20,000Hz

Answer 1

The correct option is A 20 - 20,000Hz

Humans have 2 ears on either side of the head. They capture the sound waves and transmit the signal to the auditory centre (auditory cortex in the temporal lobe) of the brain. Human ears have the ability to sense sounds with frequencies between 20 Hertz to 20,000 Hertz.
