If you'll notice, the passage starts with "Proponents of the tangible-object theory of copyright argue that..."
The rest of the first paragraph and all of the second falls under what the proponents of this theory say. The author lays out their theory and what they view as an advantage in the beginning of the third paragraph.
Ultimately, however, the author counters with two objections, that are both pretty big. The theory presented earlier doesn't account for "evanescent things" which are commonly accepted as copyrightable. In addition, it does not address the idea of conceiving ideas being more important than actually putting them into tangible form.
Thus, while the author does not explicitly say "the theory is therefore misguided," his/her overall tone at the end of the passage suggests that he/she rejects the theory.
A is wrong because that's not the main thrust of the passage, but rather what the proponents say. Keep an eye out for what the author is saying, and what the author is saying others are saying. That is key in many passages. Hope this helps.
