Possible Answers:

  1. Hurricane
  2. Volcano
  3. Tsunami
  4. Cyclone

The Correct Answer:

C. A tsunami refers to powerful ocean waves caused by an earthquake, landslide, or volcanic eruption on the seafloor.

Explanation:

An earthquake, volcanic eruption, or a landslide on the seafloor generally causes A tsunami. Whenever an earthquake occurs, the seismic waves, which travel long distances between the deep and the peak of the ocean, form powerful Ocean waves.

There is no way to identify the tsunami deep into the water but above the surface that can be easily noticeable.

The constant energy is forced toward the surface whenever the wave enters, making a very tall wave. Tsunamis are less common than earthquakes but can damage civilization and nearby communities.

Whenever an engineer or an architect designs a building, they have to make sure they are not constructing it near a seacoast (having a high probability of a Tsunami earthquake) or another place with a high chance of being affected by an earthquake.
