The correct Answer is:
To determine which of the given options is a solution, we need to understand the definition of a solution and analyze the characteristics of each option. ### Step-by-Step Solution: 1. **Understanding the Definition of a Solution**: - A solution is defined as a homogeneous mixture of two or more substances. This means that the components are uniformly distributed and cannot be easily separated by physical means. 2. **Analyzing the Options**: - We need to evaluate each option provided to see if it meets the criteria of a solution. 3. **Option 1: Milk**: - Milk is a colloidal mixture where fat droplets are dispersed in water. Since it does not have a uniform composition throughout, it is not considered a solution. 4. **Option 2: Smoke**: - Smoke is a colloid consisting of solid particles dispersed in a gas. Similar to milk, it is not homogeneous at a microscopic level, so it cannot be classified as a solution. 5. **Option 3: Brass**: - Brass is an alloy made of copper and zinc. It is a solid-solid solution where the two metals are mixed uniformly at the atomic level. This meets the definition of a solution. 6. **Option 4: Face Cream**: - Face cream is an emulsion, which is a type of colloidal mixture. It consists of fat droplets dispersed in water, and like milk, it is not a homogeneous solution. 7. **Conclusion**: - Among the options analyzed, brass is the only one that qualifies as a solution because it is a homogeneous mixture of two metals. ### Final Answer: Brass is a solution.

Read the passage below and answer the following quesitons Solution is a homogeneous mixture of two or more-substances in same or different physical phases. The substances forming the solution are called components of the solution. On the basis of number of components a solution of two components is called binary solution. Solute and Solvent in a binary solution, solvent is the component which is present in large quantity while the other component is known as solute. [If water is used as a solvent, the solution is called aqueous solution and if not, the solution is called non-aqueous solution. Depending upon the amount of solute dissolved in a solvent we have the following types of solutions: Unsaturated solution a solution in which more solute can be dissolved without raising temperature is called an unsaturated solution Saturated solution o solution in which no solute can be dissolved further at a given temperature is called a saturated solution Supersaturated solution a solution which contains more solute than that would be necessary to saturate it at a given temperature is called a supersaturated solution. Of the following terms used for denoting concentration of a solution, the one which does not get affected by temperature is:
