She is asking . . . . . . . . trouble if she goes on behaving like that. A. on B. at C. in D. for

The correct answer is for.

The word “for” is used to indicate a purpose or goal. In this case, the speaker is saying that the woman is asking for trouble, which means that she is behaving

in a way that is likely to cause her problems.

The other options are not as appropriate in this context. The word “on” is used to indicate a location or position. The word “at” is used to indicate a time or place. The word “in” is used to indicate a state or condition.

Here are some examples of how the word “for” can be used in other sentences:

• I am looking for a new job.
• I am going to the store for some milk.
• I am grateful for your help.
• I am sorry for what I did.
