Answer

Brief Explanations:

Igneous rocks that form from molten material erupting onto the Earth's surface are extrusive. Trapping of air - bubbles occurs during rapid cooling of lava on the surface. Intrusive rocks form below the surface and have large crystals and coarse texture due to slow cooling. Since the rock erupted from an underground volcano and has air - bubbles, it is extrusive.

Answer:

B. extrusive
