B.The characters' choices often cause the conflicts in a story
An example of this is Finding Nemo. At the beginning of the story, we are introduced to Nemo's character. Through the events used to characterize him and his father, we see that his father is overprotective and Nemo just wants to prove that he is a strong, brave fish despite his smaller than average fin. When the challenge arises for him to touch the boat, it is not surprising that he wants to prove to everyone that he is not a coward and can swim out to it. This of course creates the main conflict in the story as Nemo is caught by divers and his father must go save him. The conflict between Nemo and his father is also developed through their development as well.
