What should Martinez do after being asked about a tenant's race, given his fiduciary responsibilities?

In this scenario, Martinez should not disclose the tenant's race because it relates to a protected class under fair housing laws. The essence of these regulations is to prevent discrimination based on race and other characteristics, ensuring that all individuals have equal access to housing opportunities. By protecting this information, Martinez upholds ethical standards in the real estate profession and adheres to the fiduciary responsibilities he has to all parties involved, especially to the tenant, who deserves privacy and protection against discrimination.

Disclosing the tenant's race could lead to discriminatory practices, which would not only violate fair housing regulations but could also harm the tenant's rights. By maintaining confidentiality in this case, Martinez aligns with the principles of fair housing, promoting fair treatment for everyone in the rental process.

The other options do not address the fundamental issue of protecting the tenant from discrimination effectively. Some suggest that only a duty of loyalty applies or focus on materiality rather than the ethical implications of sharing personal information about a protected class member. However, respecting and safeguarding a tenant's status as part of a protected class is paramount in real estate practice.
