Which of the following is included in the penalties for Criminal Mischief?

The penalties for Criminal Mischief specifically relate to actions that involve the willful destruction of property. Among the options provided, the discharge of a firearm in an occupied structure is a serious offense that poses a significant threat to public safety and directly intersects with criminal mischief. This action can lead to extensive damage and endanger lives, therefore, it falls under more severe legal repercussions often associated with criminal mischief.

The other choices reflect different offenses: damage to private property is a core element of criminal mischief, while vandalism without injury can also relate but may not encompass all the implications of criminal mischief. Theft under $100 is categorized as a different crime. Each of the other choices, while related to misconduct, does not capture the specific legal context of Criminal Mischief as effectively as the discharge of a firearm in an occupied structure does. This highlights the broader legal framework and situational gravity encompassed in the definition of criminal mischief.
