Volcanic domes grow from lava being injected into the interior of mounds of cooled lava and from the breaking out and moving down the flanks of:
A) viscous lava flows
B) runny lava flows
C) basaltic lava flows
Viscous Lava Flows
Slow-moving lava flows that have a high viscosity, leading to thick, sticky forms of lava that do not travel far from the eruption site.
Cooled Lava
Solidified volcanic material formed when molten lava cools and hardens on the Earth's surface.

Final Answer :
A
Explanation :
Volcanic domes are formed from viscous lava flows. The high viscosity of the lava prevents it from flowing far, causing it to pile up and form a dome shape as more lava is injected into the mound from below.
