Based on the statement, the conclusion that can be drawn is that without support from Congress or the President, attempts to avoid complying with laws (including those related to public services) are unlikely to succeed. Thus, the options provided regarding the legality of suspending essential services may imply that such actions would require appropriate legal backing from governing authorities.
However, none of the provided responses (suspending mail delivery, fire services, police services, or trash collection) are directly derived from the statement. The statement does not specifically make a claim about the legality of suspending these services.
Therefore, it is not possible to conclusively determine which of these services is illegal to suspend based solely on the given statement.
If you need to select an option based solely on the phrasing of the question, the best conclusion is that all of these actions would likely need Congressional or Presidential support to be deemed compliant or legal, but none of them can be definitively stated as illegal based on the provided information alone.
In summary, none of the options can be conclusively confirmed as illegal without additional context.
