Bacteria Food at Noon, Explosive Diarrhea in Afternoon!

A potluck lunch party is held at the office at noon on Thursday. Various meats, salads, breads, and desserts that were brought in earlier that morning are served. Everyone has a good time, and most of the food is consumed. By midafternoon, the single office restroom is being used by many employees who have an acute, explosive diarrhea accompanied by abdominal cramping. Which of the following infectious agents is most likely responsible for this turn of events?
(A) Escherichia coli
(B) Staphylococcus aureus
(C) Vibrio parahaemolyticus
(D) Clostridium difficile
(E) Salmonella enteritidis
(F) Bacillus cereus

I would choose B.

The speed of the symptoms development fit with the choice, also the symptoms them selves fit, the last thing is the type of food, pastries (desert) and salads (potato salad maybe? ) also fit.
