Passive retention can be described as:

Passive retention is characterized by a lack of awareness or indifference towards certain risks. This means that individuals or organizations do not actively recognize or address potential risks they face, leading them to unknowingly retain those risks. This can occur when the consequences of a risk are underestimated or when the risks don't appear to be significant enough to warrant immediate attention or action.

In this context, a passive approach does not involve making a conscious decision to accept or mitigate risks, nor does it include proactive measures to analyze risk exposure. Instead, it reflects a more passive stance, where risks are simply accepted as part of the normal course of activity without active management or insurance coverage. This is distinct from other options, which involve either intentional risk management strategies or an acknowledgment of risk.
