Answer:

C. The red mites were resistant to the effects of the insecticides.

The increase in the population of the red mite due to the application of the insecticides shows that red mite are resistance to the effect of insecticides because the insecticides did not decrease the population of the red mite but the predator of the mite die and decrease in population.
