B. Laccoliths
Explanation:
The intrusive landforms, or rather the intrusive igneous rocks, have been formed from magma that managed to cut through layers of rocks that already existed. As the magma has been cutting through, it has started to cool off inside the crust, and as it did, it solidified and formed the intrusive igneous rocks, or intrusive landforms. One of the landforms that are formed by intrusion are the laccoliths. The laccoliths have the shape of lens, or even as a mushroom, with their base part being relatively flat. The amount of magma that has built up managed to cause uplift of the land in the shape of domes.
