The best answer is C.) The strongest bugs were able to survive pesticides, reproduce and create more resistant pests.
The reason is that the strongest bugs cannot die from the chemicals that they were using and now that they still have the ability to eat they can also have babies and make more resistant pests which is also having more stronger bugs.
The farmers are seeing stronger bugs because not all bugs die to the amount of pesticide. Some areas are not spread evenly or some bugs are more resistant genetically.
C) is the best answer, because the stronger ones are reproducing in order to create new resistant bugs.
