Correct Answer: B
Solution :
Bats are extremely modified for nocturnal flight. They possess special sense organs which allow them to perceive prey and surrounding obstacles at a distance even in total darkness. Bats are supersensitive to sound and possess a natural echo-apparatus or radar system of their own. In flight, bats keep their mouth open and continually emit tremendous bursts of supersonic or ultrasonic sounds which are quite inaudible to human ear. The warning echos reflected back enable bats to locate and evade obstacles in their path.
