The answer is B because each phrase is an infinitive phrase, which is a phrase that starts with "to," which is followed by a verb. For example, in the sentence, "I like to eat ice cream," the phrase "to eat ice cream" is an infinitive phrase since it starts with "to," which is followed by a verb.
In order for a sentence to be parallel, each of the items separated by commons must be the same type of phrase. In answer choice B, all of the phrases are infinitive phrases. Note, however, that all of the phrases do not start with "to," but that's okay so long as the FIRST phrase does :)
Furthermore, in answer choice B, each phrase is correctly separated by commas, and a comma should be placed after the dependent clause "When I go to the amusement park."
The sentence is set up in a way that the dog would appear to have pink and purple dots; the adjective phrase "with pink and purple dots" should come right after the word "sweater".
"C.) He recorded public and historical events with much candor." would be the correct answer. His diary included the great Plague, the coronation of King Charles II, and many other important historical events.
