Answer: B. Benny cannot file a claim for age discrimination under the ADEA because he is a state employee.
Explanation:
Based on the information given in the question, since Benny lives in a state that has not waived sovereign immunity, thus simply means that Benny cannot file a claim for age discrimination under the ADEA because he is a state employee.
Eben though the Age Discrimination in the Employment Act protects workers that are 40 years and above and Benny is 57 years, it should be noted that in the states whereby sovereign immunity hasn't been waived, the state employees cannot due their employers as they're barred from doing so.
Therefore, the correct option is B.
