Many companies self insure against some risk. Problems which can arise from self-insurance include:

Confusion of business risks with insurable risks is a potential concern with self-insurance but is a secondary issue compared to the fundamental financial reserve problem.

When organizations self-insure, they assume the full financial risk of potential losses themselves. A common pitfall is inadequate reserve funding - organizations may underestimate worst-case scenarios or low-probability, high-impact events and fail to set aside sufficient capital to cover those losses when they occur, leaving the organization financially exposed.

Competition from insurance companies is a market condition unrelated to the internal operational risks of running a self-insurance program.

Not all of the alternatives apply as stated; option C (competition from insurance companies) is not a valid problem that arises from self-insurance itself.

This choice appears to be a truncated version of the reserve funding concept in option B and does not represent a distinct separate problem.
