Which type of insurance covers a loss of income due to illness or injury?

Disability insurance specifically addresses the loss of income that can occur due to an individual's inability to work as a result of illness or injury. This form of insurance provides financial support by replacing a portion of the insured person's income during the period when they cannot perform their job duties due to a health-related condition.

Unlike health insurance, which primarily covers medical expenses related to healthcare services and treatments, disability insurance is focused on income replacement. Life insurance provides a benefit to beneficiaries upon the insured's death, which does not directly assist those who are temporarily unable to work due to illness or injury. Property insurance protects against damages or losses to physical assets, such as homes or vehicles, and does not pertain to income loss. Therefore, the primary function of disability insurance in the context of income loss makes it the correct choice for this question.
