उत्तर
The metal zinc and tin are present in alloy Bronze.
Explanation:
While bronze is primarily an alloy of copper and tin, commercial and industrial grades often include zinc to improve tensile strength, fluidity, and casting quality. In contrast, solder consists of lead and tin, brass is made of copper and zinc only, and duralumin is an aluminium-based alloy. Therefore, among the listed options, bronze is the unique alloy that accommodates both zinc and tin in its chemical composition.
