I'm not to sure but I think its D because the first planned they can make more movies and science fiction. Call me a nerd but I think about the star wars trilogy
I believe the answer to your question above is option B - prologue. A is incorrect because c<span>haracterization is telling how the character or setting looks like, etc. C is also incorrect because a preview is when you see something and decide whether you want to watch, buy, rent it, etc. D is also wrong because trilogy means something that is played right after another. As an example a tragic Greek play. </span>
