The sentence that uses parallel structures is B) My three favorite activities are writing, reading, and going to the library.
A parallel structure means that the same form of a verb is used in a sentence, and as you can see, here only gerunds are used - writing, reading, going - they all have -ing in the end.
The other sentences don't have a parallel structure because they don't use the same forms.
