Explanation:

To solve this, we analyze each option:

• Option A: An element is defined as a substance made of only one type of atom. For example, gold (as shown in the image) is an element made of gold atoms.
• Option B: A compound is made of two or more different types of atoms chemically bonded, so it's not made of one type of atom.
• Option C: A mixture consists of two or more substances (elements or compounds) physically mixed, not a single type of atom.
• Option D: A solution is a type of mixture (usually a solute dissolved in a solvent), so it also has multiple components.
