The correct answer is D.we shall pay any price, bear any burden, meet any hardship
Step-by-step explanation:
You can identify a parallel structure because this contains a repetition of a grammatical structure or a specific pattern. This occurs in option D because the three elements listed include a verb followed by the word "any" and finally a noun. This can be seen in "pay (verb) any price (noun)", "bear (verb) any burden (noun)", and in "meet (verb) any hardship (noun". Thus, in this, there is a specific pattern that is repeated, and therefore there is a parallel structure.
