Brass is a solution in which a solid is dissolved in a solid.

Option D

Explanation:

Brass is an example of alloy, a proportionate mixture of two metals: zinc and copper. Alloys are solid-solid solutions where a metal is mixed with one or more other types of metals or non-metals to form a new material, better in mechanical and chemical properties than the original components.

Increased resistance to corrosive actions, increased strength and toughness, better electrical conductivity, wider temperature operability, etc. are some advantages of alloying. Brass is widely used in manufacturing appliance parts and tools including valves, gears and bearings.
