Answer: A. Analogy
Step-by-step explanation:
Analogies compare one thing to another in order to make a stronger point. In this example, there is an analogy used since the author is comparing "applying for jobs without experience" with "fishing without any bait". They further explain their analogy in the next sentence
The other answers also do not fit the statement. An understatement is the opposite of an exaggeration, and there is nothing big that is understated in the sentence. There is no hyperbole since there is no exaggeration of anything. Antithesis compares two things in a balanced sentence, except it is done in a contrasting way, which is different than here.
So, an analogy is most clearly shown in this passage.
