Foreign Exchange Rate as Relative Currency Value

Steps:

• Recall that foreign exchange involves trading currencies internationally.
• Identify the core concept: exchange rates measure one currency's worth relative to another.
• Evaluate choices against standard economic definitions of exchange rates.
• Select the option that precisely captures this relative valuation.

Why D is correct:

• The foreign exchange rate is defined in economics as the price of one currency in terms of another, such as 1 USD = 0.85 EUR, directly expressing relative values.

Why the others are wrong:

• A: Exchange rates apply to currency trading, not directly to goods like exports and imports.
• B: While demand and supply influence rates, this describes determination, not the definition.
• C: Governments may fix rates in some systems, but the general definition is relative valuation, not government-set value.

Final answer: D
