Answer #1

Correct answer: b. Infrasonic waves

Explanation: Elephants also produce audible waves which can be heard by us for example during trumpeting. But in order to communicate over long distance they produce infrasonic waves which have a frequency below 20 Hz. Interestingly, these infrasonic waves travel through the ground and are sensed through the feet. This is also the reason why elephants and other animals can sense earthquake before it hits because it creases infrasonic sounds.
