Answer:
The entries in Anne's diary are written between June 12, 1942 and August 1, 1944. The entries start when she got her diary, and stop when her family is found and taken away to the camp. Anne's perspective tends to grow a lot more mature. She thinks about things in a more methodical way, and understands her flaws and mistakes.
The answer is A, because the protagonist is the main character, and that's what Rider is. The other answers don't really make sense in terms of the role he plays in the story.
