None of the above

Detailed explanation-1: -A lahar is a hot or cold mixture of water and rock fragments that flow quickly down the slopes of a volcano. They move up to 40 miles per hour through valleys and stream channels, extending more than 50 miles from the volcano. Lahars can be extremely destructive and are more deadly than lava flows.
Detailed explanation-2: -Volcanic eruptions can send ash and volcanic debris into the air. Heat from the volcano can melt snow or ice and cause dangerous mudflows and debris flows called lahars. Molten rock called lava can erupt and flow downhill, destroying everything in its path.
Detailed explanation-3: -Lahars can occur with or without a volcanic eruption Pyroclastic flows can generate lahars when extremely hot, flowing rock debris erodes, mixes with, and melts snow and ice as it travel rapidly down steep slopes. Lahars can also be formed when high-volume or long-duration rainfall occurs during or after an eruption.
Detailed explanation-4: -Lahars are hot or cold mixtures of water and volcanic debris that form when volcanic materials interact with water, ice, snow, or loose wet sediments.
