Final answer:
The minimum level at which the Commission must maintain the home improvement guaranty fund varies and depends on regulatory guidelines or statutes relevant to the specific jurisdiction.
Step-by-step explanation:
The question pertains to the requirement by the Commission regarding the home improvement guaranty fund. While the specific amount can vary based on regional legislation and policy, one would generally need to reference the specific regulatory guidelines or statutes that outline the minimum financial requirements for such a fund. Without specifying the governing body or jurisdiction, it is challenging to provide an exact figure.
For a hypothetical and illustrative purpose, if we refer to the options listed in the question, an amount would have been previously established by the associated legislative framework. It is essential to consult the latest laws or regulations relevant to this topic since the minimum amount required for the home improvement guaranty fund can be subject to change.
