Which of the following offenses would lead to a Class A penalty?

The offense that leads to a Class A penalty is interference with emergency assistance. This is because interfering with emergency services can significantly hinder the response time and effectiveness of emergency responders, potentially putting lives at risk. In many legal systems, such actions are treated severely to help deter individuals from obstructing critical services that are meant to protect public safety.

Among the other offenses listed, while they may carry penalties, they do not fall under the Class A category based on the severity of their impact on emergency response operations. A false alarm to induce an emergency response, funeral service disruptions, and making silent or abusive calls to 9-1-1 may also be illegal and disruptive but are typically classified with lesser penalties in comparison to directly interfering with the efforts of emergency services to assist those in immediate need.
