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.
The correct answer is pseudo=listening. Monica pretends to listen what Garth is saying but she is not paying attention, instead on interacting with Garth she is only sayin "uh huh". In this case Monica is focused on her cell phone which avoids to have an effective communication between her and Garth.
