Which is an example of a successful hoax?

a.a woman falls down after slipping on a banana peel.
b.a radio show makes people believe aliens are invading.
c.a young boy tricks his little brother into eating a worm.
d.a con man steals money from elderly and sick people.

These words are spoken by Mephistopheles, a prince of the underworld who becomes Faustus' servant for twenty-four years after he sells his soul to Lucifer in exchange for unlimited power.

This passage appears in Act 5, Scene 1, where an Old Man appears in front of Faustus an calls him to renounce sourcery and repent, for is not to late to be saved. But Faustus sends him away, and when Mephistopheles appears, he asks the demon to torture the Old Man for offending him.

To this, Mephistopheles responds with these words, meaning that the torture will only be physical, since he cannot touch the man's soul.
