Final answer:
A 'pure risk' is an unexpected, chance occurrence over which individuals have little control, such as natural disasters or wars, contrasting with speculative, dynamic, or static risks.
Step-by-step explanation:
An occurrence economic risk over which an individual has very little control is referred to as a pure risk. Examples include unforeseen events such as natural disasters, wars, or massive unemployment. These types of risks are not speculative; individuals affected by such events seek assurance that their needs will be met so they can provide for themselves and their families.
In response to the question, a/an pure risk is one that is unforeseen, unexpected, and occurs as a result of chance. This contrasts with speculative risks, which involve a chance of either loss or gain, and dynamic or static risks which relate to changes in the economy or remain constant over time, respectively. Thus, the correct option is b) Pure risk.
