Which of the following describes a mixture formed when two liquids are combined that can dissolve in one another?

When two liquids that can dissolve in each other are combined, they form a specific type of mixture known as a miscible mixture. The term "miscible" refers to the ability of two substances to mix together in any proportion without separating into different phases. This means that when the two liquids are mixed, they create a homogeneous solution where their properties are uniformly distributed throughout the mixture.

In contrast, other terms like "immiscible" describe liquids that do not mix well, leading to the formation of distinct layers. A "solution" is a broader term that encompasses both solid-liquid and liquid-liquid combinations but does not specifically address the characteristic of the two liquids being mutually soluble. On the other hand, a "suspension" refers to a heterogeneous mixture where solid particles are dispersed in a liquid but not dissolved, meaning they can settle out over time.

Thus, miscibility specifically highlights the property of two liquids dissolving in each other, making it the most accurate description of the phenomenon in question.
