Which of the following describes the practice of blockbusting?

Blockbusting refers specifically to a strategy used by real estate agents or developers in which they encourage homeowners to sell their properties, often at below-market prices, by instilling fear that an influx of minority residents will lead to a decline in property values. This practice exploits racial prejudices and perpetuates racial segregation, making it a discriminatory and unethical tactic.

By focusing on the fear of declining neighborhood desirability tied to the arrival of minority groups, the practice aims to create urgency for homeowners to sell. The correct answer highlights this core aspect of blockbusting, providing a clear picture of how the practice operates in real estate markets.

In contrast to this, the other options describe positive strategies or legal practices that do not align with the definition of blockbusting. For instance, options that suggest promoting diversity or improving access for minorities reflect a broader goal of equality and inclusivity in housing, which stands in stark contrast to the fear-based tactics of blockbusting.
