C Correct answer
Explanation

Aluminium is the most abundant metal in Earth's crust at about 8% by mass, though it's never found free in nature. It's always combined with oxygen and other elements in compounds like bauxite. While iron is more abundant in the entire Earth (including the core), aluminium dominates the crust specifically where we can access it.
