Correct Answer: Expense

Solution : The correct choice is the fourth option .

Profit means the amount of money gained from a business activity after subtracting all expenses, whereas expense means the costs incurred during business operations that reduce overall profit. So, in this case, expense is the opposite of profit because expenses reduce the amount of profit.

The meanings of other options are as follows:

Earnings: It refers to the money a person or business receives for goods or services provided.
Amount: It is a generic term indicating a quantity of something.
Sale: It refers to the act of selling goods or services.
