Examples of precious metals:

• A. Platinum, gold and silver
• B. Copper, tin and nickel
• C. Iron, cobalt and nickel
• D. Aluminum, zinc and lead

Answer: (A)

Metals labeled as precious are typically rare, durable, and have long-standing value as money, jewelry, or reliable stores of wealth. Platinum, gold, and silver fit that description well. Gold and silver have a long history as monetary metals and widely used stores of value, while platinum is rarer and highly valued for both jewelry and specialized industrial applications. All three resist corrosion and can be refined, contributing to their enduring worth.

The other groups are generally abundant and primarily used for industrial purposes rather than as stores of wealth. Copper, tin, and nickel are common in industry and alloys but don’t carry the same prestige or scarcity. Iron, cobalt, and nickel are essential in many technologies and manufacturing processes, yet iron is extremely abundant and the others are more about practical use than prized value. Aluminum, zinc, and lead are plentiful and inexpensive, making them less likely to be classified as precious metals.
