A person's regular income is best defined as what?

The correct answer is that a person's regular income is best defined as capacity. In the context of financial assessments, "capacity" refers to an individual's ability to repay debt, which is primarily influenced by their income. Regular income is a key factor in determining whether a person can manage monthly payments for loans or credit obligations. Lenders often evaluate this aspect when deciding to extend credit or loans, using regular income as a measure of financial stability and repayment ability.

On the contrary, the other concepts like character, capital, and collateral relate to different aspects of creditworthiness. "Character" pertains to a person's reputation for repaying debts, "capital" refers to the financial assets or net worth a person possesses, and "collateral" is an asset pledged by a borrower to secure a loan. Each of these plays a role in the overall assessment of a person's financial situation, but capacity specifically deals with ongoing income, making it the most appropriate term in this context.
