Bats are capable of flying safely in total darkness without bumping into walls or obstacles. Which mechanism enables them to do this?
  1. They emit ultrasonic sounds and navigate using the reflected echoes
  2. They have special eyes that amplify faint light in the dark
  3. They sense thermal radiation given off by cold walls
  4. They rely on wind currents detected by their wing feathers

Solution

Bats use echolocation by emitting high-frequency ultrasonic sounds and listening to the echoes reflected from obstacles.
