A disability income insurer assigns applicants to occupational classifications (for example, class 1 for low-risk office work and class 5 for hazardous construction work). This practice reflects the principle that:

Why A is correct

Occupational classification is a core underwriting tool for disability income insurance. The insured's job is a hazard — a condition that affects the probability of disability — because some occupations involve greater physical risk, stress, or exposure than others. By grouping similar occupations into classes, the insurer can rate premiums fairly: higher-hazard classes pay higher premiums. This is the law of large numbers applied through risk classification; the occupation does not itself cause the disability, and it is not the loss the policy pays.

Why the other options are wrong

• B) A peril is the actual event that causes the loss, such as an accident or sickness; occupation is the condition that makes the event more likely.
• C) Insurable interest concerns the financial relationship between the person buying coverage and the risk insured, not the insured's occupation class.
• D) The loss is the financial consequence of disability — lost income; occupation is a risk factor, not the covered loss itself.

Memory hook

Occupation grades the odds: steel girder beats desk job. Higher hazard class, higher premium.
