Final answer:
The EPA's lead pre-renovation rule applies to residential homes built before 1978. Hence the correct answer is option A
Step-by-step explanation:
The subject of this question is Environmental Protection Agency (EPA) regulations related to lead-based paint in residential homes. Specifically, the question is asking about the application of the lead pre-renovation rule based on the construction year of homes.
According to EPA 747-B-99-004, the lead pre-renovation rule applies to residential homes built before 1978. This means that if a home was built before 1978, the lead pre-renovation rule would be applicable.
For example, if a home was built in 1965, the lead pre-renovation rule would apply. However, if a home was built in 1985, the rule would not apply.
Hence the correct answer is option A
