Final answer:
The correct answer to the question is c) Foreign Corrupt Practices Act, which prohibits U.S. companies from bribing foreign officials and mandates accurate record keeping of transactions.
Step-by-step explanation:
The law that makes it illegal for employees of U.S. companies to offer or make questionable contributions to political decision makers in foreign nations is the Foreign Corrupt Practices Act (FCPA). Hence, the correct answer to the question is c) Foreign Corrupt Practices Act. The FCPA was enacted to prevent corruption and promote transparent international business practices. It prohibits bribery of foreign officials and requires companies to maintain accurate records of transactions. Due to the importance of compliance with these regulations, it is crucial that U.S. companies are knowledgeable about their obligations under the FCPA when operating in a global context to avoid legal and ethical violations.
