Which of the following should not be asked on a rental application?

The correct answer indicates that all the listed items should not be asked on a rental application due to legal and ethical considerations. In the context of housing and rental practices, the Fair Housing Act prohibits discrimination based on race, color, religion, sex, national origin, familial status, and disability.

Asking for details about race or color can lead to discriminatory practices and violate these laws. It is essential for rental applications to focus on relevant criteria, such as financial stability, rental history, and the ability to pay rent, instead of personal characteristics that do not affect a tenant's ability to fulfill their lease obligations.

In addition, inquiring about the number of children can imply discrimination against families with children, as it relates to familial status under the Fair Housing Act. Thus, all the items included in the question are inappropriate to ask on a rental application, ensuring compliance with fair housing laws and promoting equal treatment for all applicants. This practice helps maintain a fair, equitable, and non-discriminatory rental process.
