A farmer sprayed his crops with an insecticide multiple times to reduce the damage caused by a certain species of insect. Each
time the farmer used the insecticide, fewer insects died.
Why did the insecticide kill fewer insects each time it was used?
OA
Insects in the population that were resistant to the insecticide were killed and could not reproduce
Insects in the population that were resistant to the insecticide lived and reproduced.
OB
OC.
None of the insects in the initial population were resistant to the insecticide
OD.
All of the insects in the initial population were resistant to the insecticide.

B. Insects in the population that were resistant to the insecticide lived and reproduced.

Explanation: What you just asked is a serious problem that many farmers are facing today. As more insecticide and pesticides are sprayed, some insects may survive and pass their genetic traits of resistance to their offspring. Also known as pesticide resistance, this is an event of what is known as evolutionary natural selection. It's when the strongest can pass their traits to their offspring and therefore assure that their species are gonna survive. Not all insects who were sprayed from the insecticide died, so the surviving ones were able to pass their genes to their offspring, and their offspring will be able to resist the insecticide.
