The correct option is B disaster
A disaster is a sudden calamitous event that brings about great damage, loss, or destruction to lives and/or property. Examples of the same include tsunamis, floods, earthquakes, etc.
An accident typically refers to incidents that occur on a much smaller scale. Plagues may be considered to be disasters, however, they do not cause damage or destruction to property. Financial crises do not cause damage or destruction to property.
