The sentence that contains a parallel structure would be as follows:
D). Mekhi finished his chemistry homework and then finished his essay.
What is Parallelism?
Parallelism is described as the grammatical form in which phrases or words having equivalent or similar structures are proffered.
The last sentence i.e. "Mekhi...essay" employs a parallel structure as the similar phrases "finished...chemistry homework" and "finished...essay" are employed in the first and the latter part of the sentence.
This assists in giving equal significance to the ideas divided into different elements of the sentence.
Thus, option D is the correct answer.
