The correct option is (2).
Explanation:
A mixture consists of two or more distinct substances combined together.
Mixtures can be categorized into homogeneous or heterogeneous.
When the solute particles are evenly mixed within the solvent, it’s classified as a homogeneous mixture.
In contrast, if the solute particles are not evenly distributed within the solvent, it’s referred to as a heterogeneous mixture.
Furthermore, a solution represents an even dispersal of particles within the medium, resulting in a clear mixture.
A compound consists of two or more different atoms that are chemically bonded together, while an element comprises only one type of atom.
Therefore, we deduce that a mixture is the term associated with matter that can be heterogeneous.
