Q. Bats can sense obstacles because they produce
✅ Correct Answer: (B)
Ultrasonic sound waves
Explanation:
Bats use a technique called echolocation to navigate and detect obstacles, especially in the dark.
- They emit ultrasonic sound waves (sound waves with frequency above 20,000 Hz, which is beyond human hearing).
- These sound waves bounce off objects and return to the bat's ears, helping them understand the size, shape, and distance of the object.
