That is a full answer on your question hope it helps
I also concur that answer B has an error.
B: he was going to give...
So lets rewrite the whole thing. In order to prepare for the speech he was going to give to all of the parents and teachers at the school, George practiced speaking in front of a group of his friends.

There are many books in which I could pull from, but the best example would be The Hobbit by J.R.R Tolkien. Tolkien throws the reader into a mystical world set in Middle Earth. We are introduced with a Hobbit who enjoys a quaint simple life. Like many Hobbits, Bilbo Baggins does not like adventures, as it is not in their "nature." But Gandalf comes by to prove otherwise. During the novel, Bilbo is recruited by Gandalf to help a pack of Dwarves reclaim their lost home. When Bilbo accepted this journey, we are already seeing Bilbo's true colors coming through. Bilbo scurries along to meet the rest of his party as the entirety of Bag End shuns him. A great example of Bilbo's character in the dark is when he is literally in the dark. His quick thoughts are what saves him from being Gollum's next meal when he falls into his cave. Bilbo saved his own life that day because of his witty puzzles and quick actions against Gollum. At heart, Bilbo is an adventurer, just like the Took side of his family. With the help of a couple of new friends, Bilbo was able to show his "true character in the dark" to the world
