Concept: A laccolith is an intrusive igneous landform created when magma is forced between rock layers.
Explanation:First, identify the landform described.
It has a dome-shaped upper surface and a flat, level base.
This shape forms when thick, viscous magma pushes upward without breaking through the overlying layers.
The magma cools and solidifies below the surface as a large igneous mound.
Among the options, this feature is known as a laccolith.
A lopolith has a concave, basin-like shape, while a phacolith is a lens-shaped intrusion in folded rocks.
A batholith is an enormous, irregular intrusion with no definite floor.
Therefore, the correct match is laccolith.
Answer: A. Laccolith
