• B. They make use of the tongue to see
• C. They send sound signals through the air and detect the reflected ones
• D. They use the sensation of touch to see

Answer 1

The correct option is C

They send sound signals through the air and detect the reflected ones

Bats produce high frequency sound waves and then listen for the echo. When an echo comes back quickly, it means that some obstacle is close by. By listening to the echoes of their clicks, bats can even detect flying insects.

This technique is called echolocation.
