Select the sentence that illustrates the proper use of parallel structure.

my father can cook, clean, and build a rocket.
my father can cook, he can clean and build a rocket.
my father can cook, he is good at cleaning, and build a rocket.
my father can cook, clean, and he can build a rocket.

The sentence that illustrates a proper use of parallel structure is, "My father can cook, clean, and build a rocket." This indicates a parallel structure because all the verbs in the sentence take the same form or pattern. The word "can" should only be used once, and this already applies to all the verbs in the sentence.
