Answer:
d. Sarbanes-Oxley Act
Step-by-step explanation:
In the case of whistle-blowing, Sarbanes-Oxley Act offers protection for employees against retaliation from company they work for.The major reason for this protection in the Sarbanes-Oxley Act is to make sure employees report irregularities in their companies to appropriate without fear of being punished by the employers.
Other acts do not provide relevant section for protection of employees against retaliation in case of whistle-blowing.
So Enrico was counting on current law, under the same Sarbanes-Oxley Act to protect himself against company retaliation.
