What is a liability in business terms?

A liability, in business terms, refers to an obligation that a company owes to external parties, which can include loans, accounts payable, mortgages, or any other forms of debt. This definition is critical for understanding a company's financial position, as liabilities represent future sacrifices of economic benefits that the entity must provide to creditors.

Option B accurately captures this concept, highlighting that a liability specifically involves a commitment to pay money to someone else. This could be immediate or long-term and affects the company's cash flow and financial health.

In contrast, other options do not align with the established definition of a liability. Assets owned by the business represent resources that generate future economic benefits, whereas liabilities signify what the business owes. Similarly, investments made in the company from stakeholders may enhance the company's equity but do not constitute liabilities. Sources of revenue refer to income generated, which is entirely separate from the concept of owing money, as liabilities are not intended to generate income but rather reflect debts to be settled.
