Which term describes the act of intentionally setting fire to property?

The term that describes the act of intentionally setting fire to property is "arson." Arson refers specifically to the criminal act of deliberately setting fire to buildings, vehicles, or other property with the intent to cause damage or destruction. This act is not only illegal but also considered a serious offense due to the potential for harm to people, the environment, and neighboring properties.

In the context of criminal law, proving arson typically requires demonstrating that the fire was set willfully and maliciously. This involves establishing motive and intent, which distinguishes arson from accidental fires. Understanding this definition is crucial for law enforcement, as it forms the basis for investigation and prosecution related to fire-related crimes.

The other terms provided do not accurately capture the legal implications and definitions relevant to the act of intentionally setting fire. "Incendiary act" may describe similar actions but is broader and less commonly used in legal contexts. "Firecrime" is not a standard legal term, and "property damage" refers to any harm done to property without the specific implication of it being caused by deliberate fire-setting.
