Disclosures of seismic hazards and earthquake fault areas are?

Disclosures of seismic hazards and earthquake fault areas are mandatory. In areas where seismic activity is a potential risk, it is important for property owners to provide disclosure to potential buyers or lessees. This helps ensure that buyers and lessees are fully informed about any potential risks before making a decision. Options A, C, and D are incorrect because they either suggest that disclosure is not necessary at all, or that it is only necessary for certain types of properties. In reality, disclosure is mandatory for all properties in areas with potential seismic hazards.
