The <em>correct answer</em> is:
Risk.
Explanation:
All types of insurance, home, auto, life, etc., are based on the risk a company takes in providing the insurance.
Each person has a specific risk of being in an auto accident. This risk can be raised or lowered by specific behaviors, different types of cars, age of the driver, etc.
Each person has a specific risk of losing their home. This can be based on the location of the home, the materials used in construction, etc.
These risk factors will raise or lower the amount a person pays in premiums, so that the company does not lose money.
