Answer: It repeats the word "ask" in sentences with similar structures.
Explanation: The second and fourth options are completely unrelated with the concept of parallelism. The first and third options, on the other hand, are both related to parallelism, but the third option must be discarded because the contrast between "ask" and "ask not" is not repeated in each of the paragraphs; only the verb <em>ask</em> in its imperative form is repeated in each sentence.
