Final answer:
CERCLA applies to environmental cleanup situations, such as a residential property with a buried oil tank, and not to issues of discrimination or predatory lending.
Step-by-step explanation:
The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) primarily applies to situations involving the cleanup of hazardous substances. Among the options provided, CERCLA would typically be relevant to a residential property with a buried oil tank (Option A). This is because the presence of a buried oil tank poses the risk of environmental contamination, triggering the need for remediation under CERCLA.
The other options, such as discriminatory practices in lending and real estate, pertain to different areas of law. These issues are typically addressed under anti-discrimination laws like the Fair Housing Act and regulations governing lending practices. CERCLA, on the other hand, is specifically designed to address the cleanup and liability associated with hazardous substances, making it applicable to scenarios involving potential environmental contamination.
