Which of the following animals can locate an object b the echo of their sound?

Bats make echolocation calls with variable frequencies that are regularly modulated, as well as constant frequencies (CF calls), which are pitch-specific (FM calls). The majority of bats generate complex cries that combine CF and FM elements. High-frequency cries provide the bats with more precise information, such as the size, range, position, speed, and direction of a prey's flight, even though low-frequency sounds travel farther than high-frequency ones. So, these sounds are employed more frequently. It is possible for the Little Brown Bat (Myotis lucifugus) to produce such a loud sound.
