Answer: (B)

Verified step by step guidance

1. Understand the concept of an age pyramid: An age pyramid is a graphical representation of the age distribution within a population. It typically displays the number of individuals in different age groups, separated by gender, and can provide insights into the population's structure.
2. Analyze the shape of the age pyramid: The shape of the pyramid can indicate whether a population is growing, stable, or declining. A broad base suggests a high number of young individuals, indicating potential for population growth. A narrow base may suggest a declining population.
3. Consider the implications for resources: A population with a large number of young individuals may require more resources related to education and childcare. Conversely, a population with a larger elderly segment may need more healthcare and retirement services.
4. Evaluate future population trends: By examining the current age distribution, predictions can be made about future population changes, such as potential increases in birth rates or shifts in the workforce age group.
5. Recognize limitations: While an age pyramid can provide valuable insights into population dynamics and resource needs, it cannot predict exact numbers of births and deaths or determine genetic diversity.
