Money Supply

Fiat money is currency that has no intrinsic value and is not backed by any physical commodity such as gold or silver. It derives its value solely from the trust placed in the government that issues it.
An example of fiat money would be the paper currency or coins issued by a government, such as the Indian Rupee or US Dollar.
Fiduciary money, on the other hand, is money whose value is derived from the trust and confidence people have in the institution that issues it. It is not backed by physical commodities but rather by the promise of the issuing authority.
Examples of fiduciary money include checks, promissory notes, and other financial instruments that are used as money because people trust the issuer.
Option D is incorrect because fiat money is not redeemable for gold or silver, which was the case before the gold standard was abandoned.

A fixed exchange rate system refers to a situation where a country's currency value is tied to another major currency or a basket of currencies, or is fixed to the price of a commodity like gold.
One of the key benefits of a fixed exchange rate system is that it provides exchange rate stability, which is crucial for international trade and investment.
With a stable exchange rate, businesses and investors are more confident about the value of foreign exchange transactions and can plan their operations and investments accordingly.
On the other hand, if exchange rates fluctuate unpredictably, as suggested in option 2, it can create uncertainty in international trade.
Governments do have some control over monetary policies even in a fixed exchange rate system, making option 3 incorrect. Similarly, option 4 is incorrect because a fixed exchange rate system helps control inflation by maintaining stable currency values.
