A small country can have a higher population density than a large country.

The statement is True. Population density is calculated by dividing the total population of a country by its land area. Therefore, a small country with a high population can have a higher population density compared to a large country with a lower population. This is because the population is concentrated in a smaller area, resulting in a higher number of people per square kilometer or square mile.

For example, consider Country A with a land area of 100 square kilometers and a population of 10,000 people. The population density of Country A would be 100 people per square kilometer. Now, let's compare it to Country B with a land area of 1000 square kilometers but a population of only 5,000 people. The population density of Country B would be 5 people per square kilometer. In this scenario, even though Country B is larger in size, Country A has a higher population density.

It is important to note that population density alone does not determine the quality of life or the overall development of a country. Other factors such as infrastructure, resources, and social and economic conditions also play a significant role. However, in terms of population concentration, a small country can indeed have a higher population density than a large country.

Therefore, the correct answer is A.
