I believe that the most fitting answer for this question would be A, reading from the script. I remember I gave a speech one time and I read almost entirely from a page that I had written beforehand. It was judged as much weaker as a speech that I had memorized beforehand. In addition, varying your delivery can add interest and keep your audience engaged. Notecards are more effective than reading from a script, as you will not be reading word-for-word and will only be using your notecards as jumping-off points. Hope this helps.

When a character starts the work talking directly with the reader, we can perceive an affinity effect between narrator and reader, leaving the work more personal and with a more confident effect. The reader, then, begins to be part of the work, as a person who is being confidant of the narrator and receiving all the report first hand.
I think it would be answer D, to introduce an idea because it's introducing the idea of a Venus Fly Trap's diet.
