• Kilauea
• Mauna Loa

Explanation:

• Kohala: Incorrect. Kohala is considered extinct, as it has not erupted for over 60,000 years.
• Kilauea: Correct. Kilauea is one of the most active volcanoes in the world and has been erupting frequently in recent history.

Part D

The question asks for the single most immediate effect on lava's ability to solidify, but no options are provided. Generally, the most immediate effect on lava's ability to solidify is its temperature. As lava cools, it begins to solidify. Other factors that can influence solidification include the composition of the lava and the surrounding environmental conditions, such as air temperature and the presence of water.
