The correct answer is C. Erika likes jogging, hiking and reading.
Explanation:
In language, parallel structure occurs as there is a similarity in the grammatical forms used in elements of the same importance. This means a specific grammatical form is used to present a set of elements in the same sentence, for example, "I bought three books, one apple, and two pens" uses parallel structures because each element contains a number followed by a noun. This implies, the sentence that has a correct parallel structure is "Erika likes jogging, hiking and reading" because in this all the activities "jogging, hiking and reading" are included using -ing forms.
