The correct answer is C. Using the same verb tense throughout a sentence
Explanation:
Parallel structures refer to structures that include the same grammatical pattern this implies using the same verb tense or the same grammatical form. For example the sentence "Susan and Same like playing chess, going to the park, and skating in the park" has a parallel structure because in this sentence the elements "playing chess", "going to the park", and "skating in the park" have the same structure as they include an -ing verb and a complement. Thus, having a parallel structure means using the same verb tense through a sentence or the same pattern.
