Forensic chemists are analyzing blood samples taken from a murder victim. They run tests for any trace of substances that do not naturally occur in the bloodstream. Nothing odd registers but they do find extremely high levels of caffeine. What does this most likely indicate about the murder victim?

A) They drank a lot of coffee.
B) They worked on a coffee bean plantation.
C) They were poisoned with powdered caffeine.
D) Someone put arsenic in their coffee.
