{'igneous rock': [1, 0, 1, 4], 'shale': [1, 0, 0, 0], 'granite': [8, 0, 2, 5], 'marble': [2, 0, 0, 0], 'type': [5, 0, 3, 14], 'halite': [0, 0, 0, 2]}

The correct answer is option-3: Granite.

Granite is a type of igneous rock. Igneous rocks are formed from molten rock, also known as magma, that cools and solidifies. Granite is composed mainly of quartz, feldspar, and mica minerals. It has a granular texture, with visible grains of different minerals. Granite is a common rock found in the Earth`s continental crust and is often used as a building material due to its durability and aesthetic appeal. It is usually light-colored and has a coarse-grained structure.

Option-1, Marble, is not a type of igneous rock. Marble is a metamorphic rock that forms from the recrystallization of limestone or dolomite.

Option-2, Halite, is a type of sedimentary rock formed from the precipitation of salt crystals.

Option-4, Shale, is also a sedimentary rock formed from the compaction of clay, silt, or mud.

Therefore, the correct answer is indeed option-3: Granite.
