Question

Bat can fly in night, because

• A. It has strong sense of sight.
• B. Strong sense of smell.
• C. It can hear high velocity sound waves.
• D. It can produce high velocity sound waves and perceive them.

Answer 1

Answer: (D)

It can produce high velocity sound waves and perceive them.

Bats are good at flying at night because they use ultrasonic sound rather than sight to navigate. They possess radar system or biosonar which helps to determine where the echoes are coming from by producing ultrasonic sound. This is known as echolocation. Hence, option D is correct.
