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

Answer: C

Explanation:

Properties built before 1978 require disclosure of lead-based paint hazards.

Sellers and license holders must disclose lead-based paint hazards on all properties built before 1978, as this is when regulations regarding lead-based paint began to be enforced more stringently.

A) 1976

This option is incorrect because the requirement to disclose lead-based paint hazards applies to properties built before 1978, not 1976. While 1976 is close, it does not align with the regulatory standard established by the EPA.

B) 1974

Option B is also incorrect, as it does not meet the established deadline of 1978. Properties constructed before 1974 do require disclosure, but 1974 itself is not the correct year that triggers the requirement.

C) 1978

This option is correct because the federal law mandates that sellers and license holders disclose lead-based paint hazards in properties built before 1978. This regulation was put in place to protect public health, especially for children who may be exposed to lead.

D) 1972

This option is incorrect because it predates the critical year of 1978. Although properties built before 1972 must still be evaluated for lead hazards, the specific requirement for disclosure is linked to the 1978 cutoff.

Conclusion

The correct answer is definitively 1978, as it marks the year by which sellers must disclose lead-based paint hazards in older properties. All other options fail because they do not correctly reflect the established legal requirement, thus highlighting the importance of understanding the regulatory timeline regarding lead-based paint hazards.
