Answer:
The correct answer is letter "A": ERISA requires each employer to establish a pension plan.
Explanation:
The Employee Retirement Income Security Act (ERISA) is a U.S. regulation that sets boundaries on the use of Americans' retirement assets to make sure those funds are not misused. If that situation arises, thanks to the ERISA employees can sue retirement plan institutions for the harm.
Among its different regulations, the ERISA also requests employers to select a retirement plan for their employees.
