Final answer:
None of the options given are correct. The purpose of preventing discrimination in credit extension is found in the Equal Credit Opportunity Act (ECOA), not in the Clean Air Act, The Food Safety Modernization Act, the Civil Rights Act of 1964, or the National Labor Relations Act.
Step-by-step explanation:
None of the options provided are correct. The act that aims to prevent discrimination in credit extension is the Equal Credit Opportunity Act (ECOA). None of the acts listed - the Clean Air Act, The Food Safety Modernization Act, the Civil Rights Act of 1964, and the National Labor Relations Act - primarily address discrimination in credit extension. These acts are related to environmental protection, food safety, civil rights, and labor relations, respectively. The ECOA makes it illegal for any creditor to discriminate against any applicant from any type of credit transaction based on race, color, religion, national origin, sex, marital status, age, because all or part of the applicant's income comes from any public assistance program or because the applicant has, in good faith, exercised any right under the Consumer Credit Protection Act.
