The choice that is NOT evidence to show that populations change over time is "antibiotic-acceptable bacteria."
The other options—pesticide-resistant insects, antibiotic-resistant bacteria, and herbicide-resistant plants—are examples of populations that have evolved in response to selective pressures (pesticides, antibiotics, and herbicides, respectively). In contrast, "antibiotic-acceptable bacteria" does not imply any evidence of change or adaptation; rather, it suggests the absence of resistance, which wouldn't demonstrate evolutionary change.
