Supported, because Dostoyevsky believed only fully realized artistic works could fulfill their goals. So if a writer has a goal of serving a political view, in order to successfully serve that view, the work must be artistic. Dostoyevsky considers “artistic” to mean well-written.

Dostoyevsky disagrees. He doesn’t think a political purpose is necessary in order for a work to be artistic.

A work of art could fail to be well written for other reasons. We have no reason to think Dostoyevsky believes all works that aren’t well written serve political views.

Not supported, because Dostoyevsky doesn’t believe that all works that serve political views are not well written. Whether a work is well written depends on whether the writer has successfully expressed his thoughts in characters and images.

Whether a work is well written depends on whether the writer has successfully expressed his thoughts in characters and images. (Notice that this is the contrapositive of (D). Since (D) and (E) mean the same thing, neither of them can be correct, because otherwise there would be two correct answers.)
