In which situation can per person resource availability be low even with low density?

Correct answer: When resources are very limited such as a dry water scarce area

Direct answer: Option A is correct. Low population density only tells us that relatively few people live in each unit of area. It does not tell us that useful resources are plentiful. A dry region may have few people but also very little water, poor soil, scarce vegetation and limited services. When resources are divided among the people who need them, each person may still have low availability. Option A is correct because a water-scarce area can have low density and low resources per person. Option B suggests abundant water and land, so it points toward better availability, not low availability. Option C says services are nearby, which generally improves access. Option D says farming is very fertile, which suggests productive land. The key lesson is that population density and resource availability are separate ideas. Always examine both the number of people and the amount of usable resources.
