Correct Option: D. Population is increasing more than resources in the country Detailed Explanation: To understand why option D is the correct answer, we need to define what overpopulation means. Overpopulation occurs when the number of people in a given area exceeds the capacity of that area to sustain them with adequate resources such as food, water, shelter, and other necessities for a decent quality of life.

1. Population Growth vs. Resource Availability:
2. Overpopulation is fundamentally about the relationship between population growth and resource availability. If the population grows at a rate that outpaces the growth or availability of resources, then the country is considered overpopulated.
3. For example, if a country has a rapidly increasing population but its agricultural output, water supply, and infrastructure do not keep pace, then the country will face shortages, leading to overpopulation issues.
4. Understanding the Other Options:
5. Option A: The rate of birth is high:
   • While a high birth rate can contribute to population growth, it does not automatically mean that a country is overpopulated. A country can have a high birth rate but also have sufficient resources to support that population. Therefore, this option is not a definitive indicator of overpopulation.
6. Option B: The death rate is low:
   • A low death rate can lead to population growth, but similar to option A, it does not directly indicate overpopulation. If a country has a low death rate but also has a robust economy and ample resources, it may not face overpopulation issues. Thus, this option is also insufficient on its own.
7. Option C: The growth rate is high:
   • A high growth rate indicates that the population is increasing rapidly, but it does not specify whether the resources are sufficient to support that growth. A country could have a high growth rate and still maintain a balance with its resources. Therefore, this option is not a clear indicator of overpopulation.
8. Conclusion:
9. The essence of overpopulation lies in the imbalance between population growth and resource availability. Option D encapsulates this idea by stating that overpopulation occurs when the population increases more than the resources available in the country. This imbalance leads to various socio-economic issues, including poverty, environmental degradation, and reduced quality of life.

Revision Summary:

• Overpopulation occurs when the population exceeds the capacity of resources to sustain it.
• Option D is correct because it directly addresses the imbalance between population growth and resource availability.
• High birth rates and low death rates do not necessarily indicate overpopulation without considering resource availability.
• A high growth rate alone does not imply overpopulation if resources are adequate to support the population.
