A Correct answer
Explanation

Bats produce ultrasonic sounds above 20 kHz for echolocation, which is beyond the upper frequency limit of human hearing (approximately 20 kHz for infants, decreasing with age). These high-frequency cries bounce off objects and return as echoes, allowing bats to navigate and hunt in complete darkness. The statement is scientifically accurate.
