B.

Lava, ash, and other materials from volcanic eruptions gradually build up over time. This is the correct answer. The volcanic molten material is ejected from fissures or initial cones and as the lava flows out and cools and as the pyroclastic materials solidify and tumble down the slopes, they build up the flanks of the volcanoes.
