Answer:
The correct answer is option B. favorable change in DNA of the insect.
Explanation:
At the point when a pesticide is first utilized, a little extent of the pest population may survive to introduction to the material because of their particular hereditary or genetic makeup. These surviving individuals pass along the gene resistance to particular insecticide or pesticide to next generation.
Upon introduction to pesticides, insects that don't have the resistance die eventually, in this manner permitting the insects with the resistance genes to endure and reproduce,creates more resistance insects.
Thus, the correct answer is option B. favorable change in DNA of the insect.
