What are two substances put together but not chemically combined?

It is important to understand that the material is made up of two or more separate chemicals that are not chemically connected before we can respond to the question. The two components' identities are kept the same while they are combined to create solutions, suspensions, and colloids.

Mixtures and solutions are instances of combinations of components that are not mixed chemically. Chemical bonds are necessary for the chemical combination of substances.
The term "mixture" refers to the mechanical mixing of chemical compounds without a chemical change; each ingredient preserves its chemical characteristics, although the melting point of the mixture may differ from that of the individual components. Some mixes can be broken down into their constituent parts using mechanical or thermal techniques. Azeotropes are mixes in which the separation process is challenging.

Examples of mixtures: Milk suspensions are held in place by using the pure physical forces of Brownian motion. By churning milk, these physical forces may be overcome, making it feasible to separate the components of the suspension. In the combination, there are no chemical bonds.
Solutions are created when chemicals are combined by ionic or intermolecular interactions. Physical changes can separate them, such as boiling, which helps to remove the solvent. They cannot be separated chemically and cannot be joined chemically. They are also mixtures of components that are not put together chemically.

Hence option (B) is correct.
