Explanation:

To solve this, we analyze each Earth layer:

• Option A (crust): It's the outermost solid layer (rock, soil), not liquid metals. Eliminate.
• Option B (mantle): Composed of semi - molten rock (not liquid metals). Eliminate.
• Option C (outer core): It is made of extremely hot liquid metals (like iron and nickel). This fits the description.
