Which of the following actions would constitute second-degree assault?

Second-degree assault typically encompasses a range of actions that involve the intention to cause physical harm to another individual, as well as instances where harm is caused due to reckless or negligent behavior. The nature of the crime often involves serious injury or the intention to inflict harm, along with specific circumstances that can elevate the severity of the offense.

In this context, causing serious injury with intent is clearly a key factor that aligns with the definition of second-degree assault. Intentional actions that lead to significant physical harm fall squarely within the parameters of this offense.

Additionally, causing injury to a public school employee is also recognized as a significant factor in many jurisdictions and can qualify as second-degree assault due to the specific vulnerability of public servants and the policy interest in protecting individuals who serve in educational capacities.

Thus, the inclusion of both reasons—intent to cause serious injury and the context of injuring a public school employee—supports the understanding that multiple elements can constitute second-degree assault. This makes the choice indicating that both actions meet the criteria for the offense the correct answer.
