do you think my answewr is correct

I have never studied in depth the history of this part of the world, but many others have, so I'm not sure. But between your texts and appropriate Google searches, you should be able to figure it out. (Frankly, I think it depends on what year or century this is referring to.)

The correct answer is actually neither A nor B. The Toba were not Mongolian nomads who conquered northern China, nor were they a Chinese family that battled the Xiongnu NU for control. The Toba were actually a group of people who formed a significant empire known as the Northern Wei Dynasty in ancient China.

To find the answer to a question like this, it is helpful to do some research. You can start by using reliable sources such as history books, encyclopedias, or credible websites that specialize in the topic you are interested in. By searching for information on the Toba or the Northern Wei Dynasty, you can gather more accurate details about their history and gain a better understanding of the subject.
