{'german silver': [0, 0, 2, 1], 'silver': [0, 0, 0, 1], 'copper zinc': [0, 0, 1, 0], 'alloy': [0, 0, 3, 5], 'zinc': [1, 0, 0, 2], 'nickel': [1, 0, 0, 0], 'copper': [1, 0, 1, 1], 'gold': [8, 1, 7, 14]}

German silver is an alloy that is commonly used in the manufacture of jewelry, utensils, and musical instruments. The correct answer is option 4, which states that German silver is an alloy of copper, zinc, and nickel.

Option 1 (gold and silver) is incorrect because German silver does not contain gold. Option 2 (copper and silver) is also incorrect because while copper and silver are commonly used in the production of alloys, they are not the only metals in German silver. Option 3 (copper, zinc, and silver) is partially correct because copper and zinc are indeed components of German silver, but nickel is also an essential part of this alloy.

German silver is well-known for its silver-like appearance, but it does not actually contain silver. The addition of nickel gives German silver its characteristic silver color and enhances its durability and resistance to corrosion. Overall, German silver is a combination of copper, zinc, and nickel, making it a unique and useful alloy.
