Detailed explanation-1: -B. phreatomagmatic: magma and water.

Detailed explanation-2: -ANSWER: A good analogy for a volcano eruption and the spewing of lava is the uncorking of a champagne bottle. You’ll often see at a celebratory occasion that when a bottle cork is popped, a large amount of bubbly liquid will gush out of the opening.

Detailed explanation-3: -Phreatomagmatic eruptions are a type of explosive eruption that results from magma erupting through water. The second phase of the Eyjafjallajökull eruption in 2010 was phreatomagmatic as a result of magma erupting under ice.

Detailed explanation-4: -Hydrovolcanic eruptions are volcanic eruptions that are generated from the interaction of magma and/or lava with water.

Detailed explanation-5: -"Phreatic” (or steam-blast) eruptions are driven by explosive expanding steam resulting from cold ground or surface water coming into contact with hot rock or magma.
