The correct answer is: Revenue and Expenditure.
A budget is a financial plan for a set period of time. It is used to track income and expenses, and to make sure that money is available to cover all of the necessary costs. The two key components of a budget are revenue and expenditure.
Revenue is the money that a business or organization receives from its activities. This can come from a variety of sources, such as sales, investments, or government grants. Expenditure is the money that a business or organization spends on its activities. This can include costs such as salaries, rent, and materials.
A budget is important because it helps to ensure that a business or organization has enough money to cover its costs. It also helps to track spending and make sure that money is being used wisely.
The other options are incorrect because they are not key components of a budget. Supply and demand are economic concepts that describe the relationship between the amount of a good or service that is available and the amount that people are willing to buy. Imports and exports are the goods and services that a country buys from and sells to other countries. Assets and liabilities are financial terms that describe the value of a company’s resources and debts.
