17. Sellers and license holders are required to disclose lead-based paint hazards on all properties built before:

Answer: C

Explanation:

Properties built before 1978 are required to disclose lead-based paint hazards.

Sellers and license holders must disclose lead-based paint hazards on all properties built before 1978 due to the risks associated with lead exposure in homes constructed prior to this year.

A) 1972

Option A is incorrect because the requirement to disclose lead-based paint hazards does not apply to properties built before 1972. The legislation specifically identifies 1978 as the critical year for this requirement.

B) 1974

Option B is also incorrect. Properties built before 1974 are not subject to the lead-based paint disclosure requirement, as the regulation was not in effect until 1978.

C) 1978

Option C is correct because the federal law mandates that sellers and license holders must disclose any known lead-based paint hazards for properties built before this year, highlighting the significant health risks associated with lead exposure.

D) 1976

Option D is incorrect. While 1976 is close to the correct date, it does not accurately represent the year before which disclosure of lead-based paint hazards is required; the correct year in this context is 1978.

Conclusion

The correct answer, 1978, is the year when federal regulations were established requiring the disclosure of lead-based paint hazards for properties constructed before this date. Options A, B, and D fail to reflect this critical information, which is essential for safeguarding public health in older homes.
