Final answer:

A large explosive volcanic eruption is more likely to cause pyroclastic flows. These are high-density, high-speed flows of hot lava blocks, pumice, ash, and volcanic gas that can cause considerable damage.

Step-by-step explanation:

A large explosive volcanic eruption is more likely to cause c) Pyroclastic flows. While tsunamis can occasionally be caused by undersea volcanic eruptions, and lava flows are a common feature of many volcanic eruptions, pyroclastic flows are typically associated with the largest, most explosive kinds of eruptions.

A pyroclastic flow is a high-density mix of hot lava blocks, pumice, ash and volcanic gas. It moves away from the volcano at very high speed, causing devastating damage.

The creation of lava plains, such as those on the Moon and other terrestrial planets or the Snake River basalts in the northwestern United States and the Deccan plateau in India, requires a different type of eruption where lava flows rapidly from long cracks, spreading out to form these plains.
