The answer to this is D. The middle name of Donald is Fauntleroy. For those who do not know, Donald Duck was first created in the year 1934. Clarence Nash was making some Duck voices and Walt Disney overheard him doing it. This prompted him to create the character with Nash as the person who lends his voice to the character.
There are other duck characters that were created after this such as Daisy Duck. Donald Duck also has three other nephews namely Louie, Dewey, and Huey. There are still a lot of other duck characters that were formed soon after such as Daffy Duck and even some other ducklings in other cartoons.
