(C) Neither Jane nor Henry
Neither Jane nor Henry has learned Spanish.
I think its brainstorm,and 2 more things i may be wrong though.
The answer is 2.Stan is a voracious reader, an expressive writer, and a skillful painter because in a parallel structure all of the ideas hold the same amount of importance. For example, in this sentence the ideas are that Stan is a reader, a writer, and lastly a painter.
Hope this helps and have a beautiful day!
