The Fair Housing Amendments Act of 1988 states that children must be accepted in an apartment complex, unless an exemption has been granted. An apartment complex owner wishes to qualify for the exemption. Which of the following could qualify for an exemption?

The age of tenants' grandchildren is not a relevant factor in determining whether an apartment complex qualifies for an exemption under the Fair Housing Amendments Act. This provision focuses on the age of the primary residents themselves, rather than their extended family members, and thus does not support the criteria for exemption.

Employment history of tenants does not influence the qualification for an exemption under the Fair Housing Amendments Act. This legislation is concerned with age restrictions rather than tenants' job status or employment records, making this choice irrelevant to the exemption criteria.

The economic backgrounds of tenants are not a qualifying factor for an exemption under the Fair Housing Amendments Act. The Act specifically addresses age-related occupancy restrictions, and the financial status of tenants does not play a role in determining eligibility for such exemptions.
