Parallelism is using the same grammatical structure in a series of phrases or sentences. It is used to help with clarity and can provide emphasis. The only sentence with correct parallel structure is the last one, but even it is not complete. The first sentence is not parallel because the verbs "walks" and "is taking" are not in the same form.
