Answer:
D) She cannot sue for either battery or assault
Step-by-step explanation:
Assault refers to the tort of threatening to hurt someone else. In order for assault to exist, the threat of harm must exist.
On the other hand, battery refers to actually doing harm to someone else. In order for someone to be charged with battery, he/she must have physically hurt another person.
In this case, Mary cannot sue for assault because she was not aware of the threat and therefore didn't fear any damage could be done to her.
