Among the following, which are the functions of money?

(A) Medium of exchange.

(B) Unit of account.

(C) Bartering

(D) Store of value

Choose the correct answer from the options given below:

The correct answer is (A), (B) and (D) only.

To understand why this option is correct, let us examine the primary and secondary functions of money in an economy and evaluate each statement provided in the question:

1. (A) Medium of exchange: This is one of the primary functions of money. Money facilitates trade by acting as an intermediary instrument that is widely accepted by sellers in exchange for goods and services, thereby overcoming the problem of the double coincidence of wants inherent in a barter system.

2. (B) Unit of account: This is another fundamental function of money. Money provides a common measure or standard of value of goods, services, and transactions. This allows individuals and businesses to price goods, keep financial records, and make economic calculations.

3. (C) Bartering: Bartering is the direct exchange of goods and services for other goods and services without using money as a medium. Therefore, bartering is not a function of money; rather, it is the system that money was introduced to replace.

4. (D) Store of value: This is a key function of money that allows individuals to save purchasing power over time. Money can be stored, retrieved, and exchanged at a later date, retaining its value (subject to inflation).

Based on this analysis, statements (A), (B), and (D) represent the standard functions of money, while (C) does not. Thus, the correct option is "(A), (B) and (D) only".
