What does a hazard primarily increase regarding perils?

The chosen answer describes the fundamental role of hazards in the context of insurance and risk management. A hazard is a condition or situation that increases the chance of loss or damage occurring. By increasing the likelihood of an insured peril happening as well as potentially escalating the severity of any resulting loss, hazards fundamentally affect the assessment of risk associated with a given policy.

For instance, if a property is located in a flood-prone area, the environmental conditions are considered a hazard that increases both the chances of flood damage occurring and the extent of damage that might happen if a flood does occur. This understanding is crucial in underwriting and pricing insurance policies, as insurers need to evaluate the level of risk associated with different hazards to determine appropriate premiums and coverage terms.

The other options do not accurately reflect the role of hazards in risk assessment. Hazards do not inherently increase potential financial gain, nor do they affect the duration of the insurance policy or its market value; they specifically relate to risks pertaining to loss.
