Igneous Rocks
Rocks formed from the cooling and solidification of magma or lava, classified into intrusive (slow cooling inside the earth) and extrusive (quick cooling on the surface) types, such as granite and basalt.
Nonfuel Mineral Resources

Final Answer :
B
Explanation :
Igneous rocks are formed from the cooling and solidification of magma or lava, and they are an important source of many nonfuel mineral resources such as granite, pumice, and obsidian. Option A is incorrect because limestone and shale are sedimentary rocks, option C is incorrect because plant remains form sedimentary rocks such as coal and oil shale, and option D is incorrect because some igneous rocks can be formed beneath the Earth's surface.
