• A. Density-Dependent Factors
• B. Competition
• C. Density-Independent Factors
• D. Resource Partitioning

Answer: (C)

Density-independent factors are limiting factors that affect populations in the same way, no matter how many individuals are present. These are typically abiotic forces like weather events, climate extremes, droughts, floods, or wildfires. Because their impact doesn’t depend on population size, a storm or frost can reduce a small population just as much as a large one, leading to similar proportional effects across different populations.

In contrast, density-dependent factors—such as competition for resources, predation, and disease—intensify as population size grows, because more individuals lead to more interactions and resource depletion. Resource partitioning describes how species share resources to coexist, not a type of limiting factor tied to population size. So the term that best fits factors affecting all populations similarly, regardless of size, is density-independent factors.
