Which of the following is considered a liability?

A mortgage on a property is considered a liability because it represents a legal obligation to repay borrowed money used to purchase the property. Liabilities are financial debts or obligations that a person or organization owes to others, which must be settled over time through the transfer of economic benefits, such as money or services.

In this context, a mortgage requires regular payments and is secured against the value of the property, making it a clear example of a liability on a balance sheet. Understanding liabilities, like a mortgage, is crucial in personal finance because they can impact overall financial health and net worth, influencing how assets and income are managed.

The other options, such as cash, investments in stocks, and accounts receivable, are either assets or forms of financial resources that can generate income or provide liquidity rather than obligations owed to others.
