D. Mischmetal

Answer

To determine which alloy does not contain copper, we will analyze each of the given options one by one.

**Step 1: Understand what an alloy is.**
An alloy is a mixture of two or more metallic elements, which often enhances the properties of the base metal.

**Step 2: Analyze each option.**
- **Option 1: Bronze**
- Bronze is primarily composed of copper and tin. Since it contains copper, it cannot be the correct answer.

- **Option 2: Brass**
- Brass is an alloy made of copper and zinc. Again, since it contains copper, it is not the correct answer.

- **Option 3: German Silver**
- German silver, also known as nickel silver, consists of copper, zinc, and nickel. Since it contains copper, it is also not the correct answer.

- **Option 4: Mish Metal**
- Mish metal is an alloy that primarily contains lanthanides (rare earth metals), iron, and carbon. It does not contain copper.

**Step 3: Conclusion**
After analyzing all the options, we find that the alloy that does not contain copper is **Mish Metal** (Option 4).

**Final Answer: Option 4 - Mish Metal**
