Which of the following is a key disclosure required by Regulation Z?

The finance charge is a key disclosure required by Regulation Z because it represents the total cost of credit expressed as a dollar amount. This charge includes all fees and charges associated with the loan, such as interest, points, and certain other fees, providing the borrower with a clear understanding of what the borrowing will actually cost.

By mandating disclosure of the finance charge, Regulation Z ensures that consumers can easily compare the costs associated with different credit options, promoting transparency and informed decision-making. This aligns with the core objective of the Truth in Lending Act, which is to protect consumers in credit transactions by requiring clear and understandable disclosures.

Other options, while important in the context of lending, do not constitute key disclosures under Regulation Z. Loan approval status may provide information about whether a borrower qualifies for a loan but is not mandated as a key disclosure. Appraisal value can inform borrowers about the value of the collateral but is not a required disclosure. Similarly, while credit scores are important for assessing creditworthiness, they do not fall under the specific key disclosures outlined in Regulation Z.
