C Correct answer
Explanation

Planetary differentiation is the process by which a planet separates into layers of different composition and density. During Earth's early molten state, heavier elements (iron, nickel) sank to form the core, while lighter materials (silicates) rose to form the mantle and crust. This created the layered interior structure we observe today.
