Kurt is fifty-two years old and has worked for a company covered by the Age Discrimination in Employment Act (ADEA) of 1967. He wants to bring a claim of age discrimination against his employer because he was replaced by a younger, lower-paid worker. To make out a prima facie case of age discrimination, Kurt does not have to establish that he:

a. is a member of the protected age group.
b. was qualified for the job he lost.
c. was discharged in a way that creates an inference of discrimination.
d. was replaced by someone who was below the age of forty.
