What aligns with redlining as an official practice today?

The concept of redlining is rooted in historical practices where banks and insurers would avoid investing in certain neighborhoods based on racial or ethnic demographics, effectively denying services to groups of people based on their race or the area they lived in. This practice has been officially deemed discriminatory and illegal; therefore, any form of race-based discrimination in real estate transactions or lending practices goes against current laws and is recognized as a violation of fair housing regulations.

Understanding redlining in the context of present-day legal frameworks emphasizes the importance of maintaining equitable practices in real estate, which is why the option referencing officially illegal discrimination aligns with the definition of redlining. This highlights the ongoing efforts by the government and various organizations to combat historic injustices in housing and ensure equal access to housing opportunities for all individuals, regardless of their background.
