B) Neighboring cities that did not implement a 'Recycle More' campaign also saw an average 12% increase in recycling rates during the same year.. If neighboring cities without the campaign also saw a significant increase, it suggests a broader trend or external factor (e.g., regional initiatives, economic changes) is responsible, not solely the city's specific campaign, thus weakening the mayor's claim of direct causation.
