An intrusive igneous body is a mass of igneous rock that forms from the cooling and solidification of magma beneath the Earth's surface. Examples include stocks and batholiths, which are large, irregularly shaped bodies, and dikes and sills, which are more tabular. Aphanite refers to a fine-grained volcanic rock and is not an intrusive body itself. Therefore, the correct answer would be stock or magma chamber, but not aphanite.
The largest igneous intrusive body is the batholith. Batholiths are enormous, sometimes more than 100 km squared in size, and often feed volcanoes.
Laccoliths are igneous intrusions that take the form of a dome-shaped bulge in the Earth's crust. They are formed when magma is injected into the crust and creates a lens-shaped body of igneous rock below the surface. Laccoliths are associated with volcanic activity and can affect the overlying rock layers, causing uplift and deformation.

A lens-shaped intrusive igneous mass close to Earth's surface is called a laccolith. Laccoliths are formed when magma intrudes between layers of sedimentary rock and causes the overlying rock layers to arch upwards, creating a dome-shaped structure.

A lens-shaped intrusive igneous mass that forms close to Earth's surface is called a laccolith. Laccoliths are formed when magma intrudes between rock layers and causes the overlying rock to arch upwards, creating a lens-like shape.
That description likely refers to a pluton, which is a large, circular or dome-shaped mass of intrusive igneous rock formed beneath the Earth's surface by the solidification of magma. Plutons are typically composed of granite or other coarse-grained rocks.

laccolith. It is a type of intrusive igneous rock formation that creates a dome-shaped bulge in the Earth's crust as magma pushes up the overlying rock layers.
Dikes: Tabular, discordant intrusive igneous bodies that cut across existing rock layers. Sills: Tabular, concordant intrusive igneous bodies that form parallel to existing rock layers. Laccoliths: Intrusive igneous bodies that are lens-shaped and have uplifted the overlying rock layers. Batholiths: Large intrusive igneous bodies that cover at least 100 square kilometers. Stocks: Small intrusive igneous bodies that are less than 100 square kilometers in size.

A laccolith is an igneous intrusive feature that forms when a lens-shaped mass of magma intrudes between rock layers and arches the overlying strata upwards. As the magma cools and solidifies beneath the Earth's surface, it creates a domed structure that can be exposed through erosion, revealing a characteristic mushroom-like shape.
