Several animal species can hear frequencies well beyond the human hearing range. Some dolphins and bats, for example, can hear frequencies over 100 kHz.

"Most bats use frequencies in the range 20-80 kHz, only a few bats use frequencies less than 20 kHz which is the upper limit of human hearing." 20–80 kHz.

24 авг. 2020 г. · Bats produce ultrasonic waves whose frequency range is above 20,000Hz. Therefore option 2 is correct.
