    Answer:

    D. 1, 2, 4, 5

    Read Explanation:

    The primary mechanisms that generate tsunamis involve the rapid displacement of a large body of water. Subduction zone earthquakes are the most common cause globally, where one tectonic plate slides beneath another, abruptly uplifting or down-dropping the seafloor. Other less frequent but equally devastating triggers include massive underwater landslides and significant volcanic eruptions that displace water or generate pyroclastic flows into the ocean.

    Consider the following statements about Tsunami characteristics and their impact.

    1. Tsunamis are a series of powerful ocean waves created by the abrupt displacement of a large volume of seawater.
    2. These waves have the ability to travel only short distances across oceans.
    3. Upon reaching coastal areas, tsunamis cause a highly destructive surge on land.
    4. The term 'tsunami' refers to a single, unusually large wave.
