Which of the following is a criterion for Regulation Z to apply to a loan?

Regulation Z, part of the Truth in Lending Act, is designed to protect consumers in loan transactions by requiring clear disclosure of key terms and costs associated with credit. One of the primary criteria for Regulation Z to apply is that the loan must be made for personal, family, or household use. This means that the regulation is focused on protecting individual consumers rather than businesses or commercial entities.

When a loan is intended for personal, family, or household purposes, it falls under the jurisdiction of Regulation Z, which ensures transparency in lending practices that affect consumers' financial decisions. Therefore, the correct answer highlights the consumer-oriented nature of Regulation Z, distinguishing it from loans made for commercial purposes or those without finance charges.

In contrast, loans made for commercial purposes, those lacking a finance charge, and loans where the borrower is a corporation do not qualify for Regulation Z’s protections. This ensures that the regulation focuses specifically on consumer loans, which require specific disclosures to enable borrowers to make informed decisions about their finances.
