Which sentence demonstrates parallel structure in listing actions by leaders?

• A. Beyond virtue, wise leaders display their virtues in their actions; they communicate well; they build mutual respect.
• B. Beyond virtue, wise leaders display their virtues in their actions and their speech; they communicate well; they build mutual respect as a result.
• C. Beyond virtue, wise leaders display their virtues in their actions; they communicate well; they build mutual respect.
• D. Beyond virtue, wise leaders display their virtues in their actions and their speeches; they communicate well; they build mutual respect.

Answer: (C)

Parallel structure means listing items in the same grammatical form so they read as a balanced, equal set. In this sentence, the leaders’ actions are presented as three parallel verb actions: display their virtues in their actions, communicate well, and build mutual respect. Each item uses a simple, similar pattern that keeps the rhythm steady and signals that these are three equivalent actions the leaders take. The first part introduces the subject and then the three actions follow in the same concise form, with the actions weighted equally by the punctuation (semicolons) that separates them.

Other options mix the forms: one item can pile on extra phrases or conjoin two ideas in a single item, or switch to a different sentence type for the subsequent actions. That disrupts the uniformity of the list, making the sequence feel uneven rather than a clean set of equal actions.
