A stable, widely accepted currency used in international trade (e.g., USD, EUR)?

• A. Exchange Rate
• B. Foreign Exchange Market
• C. Hard Currency
• D. Inflation

Answer: (C)

Hard currency is the term for a stable, widely accepted currency that is readily used in international trade and finance. It earns that status because it maintains value, is highly liquid, and is widely convertible, making it reliable for pricing, invoicing, and settlement across borders. Currencies like the U.S. dollar and the euro are classic examples, often used as reference currencies or reserves in global transactions.

This fits the description of a currency used broadly in international trade, not the concept of the exchange rate (which is the price of one currency in terms of another), the foreign exchange market (where currencies are traded), or inflation (the general rise in price levels). That combination of stability, convertibility, and widespread acceptance is what defines a hard currency.
