Using 'Insecticide A' to Control Insect Pests Can Lead to Selection

Using 'Insecticide A' to control insect pests can lead to selection for alleles that convey resistance. Agricultural scientists have discovered that the development of resistance, in a population of insect pests, can be hindered by rotating the use of 'Insecticide A' with other pesticides. A reasonable explanation for the effectiveness of this strategy is that

A) alleles for resistance to 'Insecticide A' are disadvantageous in the absence of 'Insecticide A'.
B) the other pesticides induce the resistant allele to mutate into a non-resistant form'.
C) resistance is an acquired adaptation, not transmitted to offspring.
D) it prevents an increase in the frequency of the resistant allele due to genetic drift.
E) resistance acquired to one insecticide may not provide resistance to a different insecticide.
