Final answer:
Nasir can sue Ladd for the tort of battery because it was Ladd's intentional action that caused harmful contact with Nasir. The intent to hit a specific person is not required for the tort of battery, as long as there was an intention to throw the rock and cause contact.
Step-by-step explanation:
The student's question pertains to the tort of battery, which is a legal cause of action under personal injury law. In the scenario given, Nasir can sue Ladd for battery because it was Ladd's intentional action of throwing the rock that resulted in hitting Nasir, albeit unintentionally.
The tort of battery requires an intentional act that results in harmful or offensive contact with another person without their consent, and it does not require the intent to harm that specific person. Therefore, since Ladd intended to hit Minh and ended up hitting Nasir, Nasir has grounds to sue Ladd for battery. Minh and the original owner of the rock are not liable since neither took part in the action that caused harm to Nasir.
