Detailed Solution

Concept: The core of the planet is its centre region. The crust, mantle, and core are the primary divisions of the planet earth. Once more, the core is composed of two parts: a liquid outer core and a solid inner core.
Question Image

While the inner and outer cores are mostly composed of iron and nickel, the mantle and crust are primarily composed of stony material. In the case of crust, the thinner portions are made of silicate igneous rocks like basalt, while the thicker portions are made of silicate rocks like granite. In the case of the mantle, silicate rocks with a high iron and magnesium content make up the composition. Above the solid inner core of the earth and under its mantle is a thick, liquid layer made of iron and nickel known as the outer core. The majority of the earth's inner core is a solid ball made of an iron-and-nickel alloy.
Hence, the correct answer is core.
