The correct answer is option (D):
Pleasure
The relationship between the first pair of words, Vindicator : Revenge, is one of action and its goal. A vindicator seeks revenge; they are the agent who performs the act to achieve the goal of revenge.
Now, we need to find a word that maintains the same relationship with Epicurean. An Epicurean is someone who pursues pleasure. They are the agent, and pleasure is the goal they seek.
Looking at the options:
Sorrow is a feeling, not a goal or a sought-after outcome.
Fright is a feeling, not a goal.
Hesitation is an action, but not necessarily a goal for an Epicurean.
Pleasure is the goal of an Epicurean.
Depression is a feeling, not a goal.
Therefore, the correct answer is Pleasure because it reflects the core principle of Epicureanism: the pursuit of pleasure and the avoidance of pain.
