Final answer:
The provided statements about the magnitudes of the forces or charges are contradictory and insufficient to determine a clear order of the charges in decreasing magnitude. Assuming the second statement is correct, the order would be C>A>B, which is not listed as an option.
Step-by-step explanation:
The question seems to concern the ranking of electric charge magnitudes in an animation that illustrates various forces. From the partial information provided, it appears that the magnitudes of forces or electric charges are compared. Based on the statements 'The magnitude of force A must be greater than the magnitude of force C, so A > C.' and 'The magnitude of force C must be greater than the magnitude of forces A or B, so AB.', these are contradictory and thus the provided information is not sufficient to accurately determine the order of charges. Therefore, if we assume that the second statement is the correct one, the charges would be in the order C>A>B, which is not presented as an option in the list provided by the student. Without further context or clarification, it is not possible to give a definitive answer.
