< b="" />Introduction< />

The question asks for the solution of solid in a solid, and the correct answer is option B - Brass. Let's explore why Brass is the correct choice.

< b="" />Explanation< />

< b="" />1. Definition of Brass< />
Brass is an alloy made primarily of copper and zinc. It is a solid solution because it is a mixture of two solid elements that form a single homogeneous phase.

< b="" />2. Composition< />
Brass typically contains around 60-70% copper and 30-40% zinc. The exact composition can vary depending on the desired properties of the brass.

< b="" />3. Solid Solution< />
A solid solution is a homogeneous mixture of two or more substances in the solid state. In the case of brass, copper and zinc atoms mix together at the atomic level to form a single solid phase.

< b="" />4. Formation of Brass< />
Brass is formed by melting copper and zinc together and allowing them to cool and solidify. During the cooling process, copper and zinc atoms mix together to form a solid solution.

< b="" />5. Properties of Brass< />
Brass possesses unique properties that make it suitable for various applications. It is corrosion-resistant, malleable, and has good electrical conductivity. These properties are a result of the solid solution formed by copper and zinc.

< b="" />6. Applications of Brass< />
Brass is widely used in various industries due to its desirable properties. It is commonly used in the manufacturing of musical instruments, plumbing fittings, electrical connectors, decorative items, and more.

< b="" />Summary< />
In conclusion, Brass is the correct answer because it is an example of a solid solution. It is an alloy composed of copper and zinc, where the atoms of these elements mix together at the atomic level to form a single solid phase. Brass possesses unique properties that make it suitable for various applications in different industries.
