What did she threaten if I didn't give her money?

The correct response indicates that the threat was a physical one, specifically involving hitting. This option aligns with the typical conversational structure where one might express fear of physical harm as a consequence of failing to comply with a request. The term "threaten" in this context implies an intimidation tactic that involves potential violence, making the option relevant and contextually appropriate.

The other options imply different forms of threats—such as legal repercussions, financial loss through theft, or social embarrassment. While these scenarios could also be seen as threats, they do not fit the context of a more immediate and personal form of intimidation expressed in the question. The focus here is on a direct, physical consequence, which is why the option involving hitting is chosen as the most fitting response.
