The correct answer is:
**A. Experiment. The variable of interest is whether a passenger's bracelet is magnetized or not.**
This scenario describes an experiment because participants are assigned to different groups (magnetic bracelets vs. non-magnetic bracelets) to evaluate the effect of the treatment (the magnetism) on the outcome (motion sickness).
