The correct response is I, II, and III.
All three can cause tsunamis:
- I. Earthquakes: The most common cause of tsunamis, particularly those that occur under the ocean.
- II. Volcanic eruptions: Eruptions can displace large amounts of water, leading to tsunamis.
- III. Landslides: Underwater landslides or landslides into the ocean can also generate tsunamis.
Therefore, tsunamis can result from any of these three events.
