Final answer:
The correct vocabulary word for the sentence provided is 'repressive' as it describes a situation where the CEO's policies are so controlling that the employees are eager to be relieved from their duties.
Therefore, option C is correct.
Step-by-step explanation:
The vocabulary word that best fits the sentence 'We couldn't wait to be relieved of our duties just so we could finally be free from the CEO's policies' is repressive. Repressive refers to a form of control that is inhibiting or restraining personal freedom, similar to the sentiment expressed about the CEO's policies. None of the other options – discord (lack of harmony), caste (a social class), or inflicted (imposed as something unpleasant) – capture the sense of oppression implied by 'finally be free from'. Therefore, the word repressive clearly fits the context provided as it denotes a situation where there is a desire to escape from controlling and restrictive policies.
