• C. infrasonic waves
• D. none of these

Answer 1

The correct option is A

seismic waves

The explanation for the correct option:

1. When an earthquake occurs, a wave of energy is released, which are known as Seismic waves.
2. It is like the undulation developed in water when you throw a stone in it.
3. Seismic waves are like those undulations that can propagate through the inside of the earth, as well as on the surface.
4. Therefore, Waves produced due to the earthquake are known as seismic waves.

The explanation for the incorrect options:

1. A shock wave is produced when the sound-producing source moves with a speed higher than the speed of sound.
2. The wave refers to an infrasonic wave that has a frequency below 20 Hz

Hence, option (a) is correct.
