Answer:
a) The act forced federal employees to pass competitive exams.
Step-by-step explanation:
The Pendleton Civil Service Act is an act of the federal government which was passed by 47th Congress of the United States. According to this act in order to serve in the government as a government official or in a civil service, people have to give competitive examinations to be appointed as a government employee rather than having ties with some politicians.
Also these employees cannot be terminated or demoted from their post due to some political reasons.
Hence the correct option is (a).
