Hint:
The interior of the structure of the earth is layered in spherical shells, it looks like an onion. Earth is the third planet distance from the sun. The earth has three layers, which are crust, mantle, core. The core layer consists of an inner core and outer core. Continental crust and oceanic crust are two kinds of crust.

Complete step by step solution:
The inner core, outer core, mantle, crust layers make up this portion of the earth.

The crust: the earth’s crust looks like the skin of an apple. It is very thin while compared to other layers. The crust made up one per cent of the earth. The crust of the earth is broken into lots of pieces called plates.
The mantle: the mantle is the layer below the crust. The mantle is the largest layer of the earth. The mantle is divided into the upper and lower section.
The core: this the centre of the earth and made up of the solid iron or nickel. The outer core is the core of the earth and is like a ball of very hot metals. The outer core is full of liquid. It is made up of iron, it is very dense. The inner core has high temperature and pressure, so metals cannot move. The inner core is solid.

Hence, the correct answer is option .

Note:
 The circumference of the earth is about miles. The crust layer’s range is about miles in depth. The mantle layer’s thickness is about miles. The inner core layer’s range is about miles in diameter. The outer core layer’s range is about miles in diameter.
