A person commits _____ when he damages any real property, or personal property worth $150 or more, by means of fire or explosive.

The correct answer is that a person commits arson when they damage real property or personal property worth $150 or more through fire or explosives. Arson specifically relates to the intentional act of setting fire to or using explosives to damage property. The law recognizes arson as a serious offense because it not only endangers property but also poses a threat to public safety and the lives of individuals in the vicinity.

In the context of your question, the key elements that constitute arson include the use of fire or explosives and the resulting damage to property. This distinguishes arson from other types of offenses that might involve property damage but do not specifically require the use of fire or explosives.

On the other hand, criminal damage to property refers to a broader category of offenses that involve the intentional destruction of another person's property without the specific use of fire or explosives. Disorderly conduct generally pertains to behavior that disturbs public peace or safety but is not related to property damage through fire. Insurance fraud involves deceitful practices to gain an undeserved benefit from an insurance policy, which does not directly relate to the act of damaging property via fire or explosives.
