Pure risk is defined as:

Pure risk is defined as a situation where there is a potential for loss but no possibility for gain. This type of risk is typically associated with events that could result in a loss, such as natural disasters, accidents, or health issues. Insurers primarily deal with pure risks, as these are the risks that can be quantified and managed through underwriting and risk management strategies.

In contrast, other types of risks might include speculative risks, which do provide the opportunity for both loss and gain, but pure risk does not. Therefore, option B accurately captures the essence of pure risk by highlighting its characteristic of presenting only a chance of loss. Understanding this distinction is crucial for professionals in the insurance and risk management fields, as it influences how risks are assessed and addressed.
