A. a developing nation
Explanation:
Age pyramids are the age structure diagrams that represent the number and proportion of people at each age in a population. The base of the age pyramids represents the population in pre-reproductive age which is from 0 to 10 years. The overall shape of an age pyramid indicates if the population is increasing, stationary, or shrinking.
The age structure diagram for a developing nation has a broad base that tapers quickly towards the top. This means that a larger percentage of the population is in the pre-reproductive age group and reproductive age group with a smaller percentage of the population in the post-reproductive age. These countries have a great chance of future population growth.

'Natural selection' can be defined as the process of selection of the organisms who are more evolved and better suited for their surroundings and are capable of producing high number of offsprings. Artificial selection can be defined as the selection of the organisms by the humans to selectively breed whether or not they are suited for the changing surroundings or not. Since, the farmer only introduced the pesticide, and the insects evolved and inherited resistance to the pesticide, this is a case of the natural selection.
