A 36 year old woman contacts the police to notify them she was responsible for a recent disastrous flood with loss of lives. What kind of delusions is she suffering from?

The key is C. Delusion of guilt. [Delusions of guilt or sin (self-accusation): This type of delusions involve feeling guilty or remorseful for no valid reason. An example would be someone that believes they were responsible for a war in another country or hurricane damage in another state. In this case, the person believes that they deserve to be punished for their sins and place full blame on themselves].
