Final answer:
The answer is A) Determine, as acting arbitrarily means to make decisions based on personal discretion without consulting others, arbitrating, or questioning.
Step-by-step explanation:
One who acts in an arbitrary way assumes the power to determine whether an action is appropriate or not. The answer is A) Determine. Being arbitrary means making decisions based on personal discretion rather than fixed rules or laws, and in the context of this question, it does not refer to consulting others, arbitrating between different parties, or questioning the action itself.
Instead, it pertains to the authority to make a decision unilaterally. This authority may not always align with John Rawls' principle of the moral Good, which suggests decisions should uphold a maximum-minimum principle aimed at fairness.
