Which factor is described as Number of possible persons in the considerations?

• A. Number of participating SAR facilities
• B. Complexity of case
• C. Number of possible persons
• D. Pollution

Answer: (C)

The factor being tested is the scale of who could be involved—the number of potential persons considered. This determines the scope of the effort: how broad data collection must be, what privacy and consent issues might arise, and how many resources are needed to cover everyone who could be affected. When there are many possible persons, planning must account for a larger outreach, more extensive sampling strategies, and stronger protections for individuals. The option that describes the number of possible persons directly matches this concept. Other aspects describe different dimensions—how many facilities participate, how complex the case is, or environmental factors like pollution—not the size of the person pool.
