Quizplus · Accepted Answer

When lava piles up near the vent and results in a steep-sided and compact structure, it is called a lava dome. Hence, option D is the correct choice. Option A, volcanic dome and option C, volcanic basin are incorrect as they do not refer to the specific type of dome formed due to the accumulation of lava. Option B, plutonic dome refers to a dome formed by the uplift of the Earth's crust due to the intrusion of molten rock (magma) at depth which is not related to the accumulation of lava near a volcanic vent.
