A: Both (A) and (R) are true, and (R) is the correct explanation of (A).
Explanation:
Alloys are mixtures because they retain the properties of their components and have variable compositions, despite the fact that their components cannot be separated by physical methods. For example, brass retains the properties of zinc and copper and has a flexible composition.

Understanding Alloys as Mixtures
Alloys are indeed classified as mixtures, despite the fact that their components cannot be separated by physical methods. Let's explore the assertion and reason in detail.
Assertion (A) Explained
- Alloys are combinations of two or more metals (or a metal and a non-metal) that are melted together.
- While they form a homogeneous mixture at the atomic level, the individual components retain their unique properties.
- The inability to separate the components using physical methods (like filtration or distillation) is a characteristic of alloys, not a disqualification from being considered a mixture.
Reason (R) Explained
- Alloys exhibit properties derived from their constituent metals, such as strength, ductility, and resistance to corrosion.
- The composition of alloys can vary, meaning that different ratios of components can yield different properties, which is a hallmark of mixtures.
- This variability in composition allows for the customization of alloys to meet specific requirements for various applications.
Relationship Between A and R
- Both statements are true: alloys are classified as mixtures, and they show properties of their constituents while allowing variable composition.
- The reason (R) effectively explains the assertion (A) by emphasizing the nature of mixtures and the behavior of alloys.
Conclusion
Thus, the correct answer is option 'A': both (A) and (R) are true, and (R) is the correct explanation of (A). Understanding this relationship enhances comprehension of material science and the properties of different substances.
