Final answer:
Life insurance applications can be rejected based on age, gender, and occupation but not typically on marital status due to anti-discriminatory laws like the Equal Credit Opportunity Act.
Step-by-step explanation:
When applying for life insurance, certain factors may be considered by insurers to determine eligibility and premiums. However, one factor that typically cannot be used as a basis for rejecting an application is marital status. While age, gender, and occupation are all common factors used by insurers to assess risk and can lead to the rejection of an insurance application, marital status generally is not. This is partly due to laws such as the Equal Credit Opportunity Act, which prohibits discrimination based on factors such as gender, race, ethnicity, and marital status in the extension of credit, and by extension, reflects a broader movement against discriminatory practices in financial services.
