Bats detect obstacles in their path by receiving the reflected

Result
Your answer: —  Â·  Correct: B
Explanation

Bats navigate and hunt using a biological sonar system known as echolocation. They emit high-frequency sound waves, specifically ultrasonic waves, which are beyond the range of human hearing [4]. These waves travel through the air and bounce off objects such as obstacles or prey [4]. The bat then receives the reflected echoes and interprets the time delay and frequency changes to determine the distance, size, and direction of the object [5]. This process allows bats to maneuver effectively in total darkness [4]. While infrasonic waves are low-frequency sounds and radio or microwaves are electromagnetic waves, bats specifically rely on the mechanical energy of ultrasonic sound waves for their biosonar [1]. This specialized sensory adaptation is essential for their survival in complex environments.
