The correct answer is A. Steering occurs when a real estate professional directs or influences prospective purchasers or tenants toward or away from particular neighborhoods or properties because of race, religion, familial status, national origin, disability, or another legally protected characteristic.

Massachusetts explicitly identifies steering away from particular properties or rental units based on protected characteristics as unlawful housing discrimination.

The agent must instead use lawful, objective criteria provided by the client—for example, price, property style, bedrooms, transportation, commuting needs, accessibility requirements, and amenities.

Option B describes redlining, which historically involves discriminatory lending, insurance, or related services based on geography. Option C describes blockbusting or panic selling.

Even when a consumer asks to be shown only neighborhoods populated by a particular racial, ethnic, or religious group, a licensee may not participate in unlawful segregation.
