The correct answer is B. We came; we saw; we conquered
Step-by-step explanation:
In grammar, parallelism or parallel construction is the repetition of grammatical structures or patterns within the same sentence, this repetition establishes a parallel relationship between different words or phrases that show all the elements have the same importance and are introduced in the same way. This grammatical constructions also make texts easier to understand and state in a clearer way the relationship between a set or list of elements and other structures. Considering this, the example that uses parallel words or phrases is B. "We came; we saw; we conquered" because in this example all the elements have the same grammatical structure (use of the pronoun "we" followed by a verb in past simple); also all the elements are separated by a semicolon and any other element is added which means there is a repetition of grammatical structures and a relation of parallelism within the elements which are the main features for parallel words or phrases.
