Entrusive refers to the process of magma or molten rock being forced into surrounding rock formations. This can result in the formation of features such as dikes, laccoliths, and batholiths. Entrusive igneous rocks are formed from this process.

I think it is "extrusive Igneous rock". Well, the magma,the hot liquid earth material which flows out through a vent(ways or cracks in the earth's crust), if on coming over to the surface of the earth, cools or solidifies, it is called "extrusive rock". If the magma, cools before coming over to the surface of the earth it is called "intrusive rock". the rocks formed this way are generally Igneous rocks. More detailed answer may follow.
