The upper limit of human hearing is normally considered to be about

Explanation:
The upper limit of human hearing is about 20,000 Hz (20 kHz). Humans generally hear roughly from 20 Hz up to this upper boundary, though the exact limit can vary with age and exposure. The other options fall outside the typical audible range: 2,000 Hz is mid-range, not the top end; 200 Hz is far below the high end; 200,000 Hz is above what humans can hear and lies in the ultrasonic region. This boundary between audible sound and ultrasound is why ultrasonic testing uses frequencies well above 20 kHz.
