The correct option is C She fell ill
Edison was 8 years old when he thought that humans could fly. He asked his teacher why humans can't fly when birds can. His teacher said that humans had no wings like birds, but Edison didn't give up on the idea. Later, he saw a bird eating worms and flew right after eating. He thought humans can fly if they eat worms. He quickly smashed some of the worms and gave it to the servant girl. He asked her to drink it and said that if she drank it, she would fly. When she actually drank the liquid, she fell ill instead of flying. Thus option C is the correct answer.
