Which if the following best explains what happens to the exchange rate of a floating currency?

The exchange rate of a floating currency is determined by market forces, primarily supply and demand for that currency in foreign exchange markets. Factors such as interest rates, inflation, political stability, and economic performance can influence these forces, causing the currency's value to fluctuate. When demand for a currency increases relative to others, its value rises, and vice versa. Consequently, the exchange rate can change frequently based on economic news and market sentiment.
