Nils Holgersson is the correct answer because the question is asking for the name of a cartoon, and Nils Holgersson is a well-known cartoon series based on the Swedish children's book "The Wonderful Adventures of Nils" by Selma Lagerlöf. The other options, such as David the Gnome, Hulk Hogan, Maya the Bee, and Care Bears, are all different cartoons and not the correct answer to the question.
