Come and help me solve this geography problem.

B the last one answered, you should read the question he asked you clearly. Word layout is the key. Let's analyze it. A consumer market, Inner Mongolia's economy belongs to underdeveloped areas, dairy products are self-sufficient and the market consumption is insufficient. C labor is cheap, although it is possible to choose C, but it is not enough to be the reason for Yili's choice, because there are still many places in the country where labor is cheaper than that, but it can be a factor. D has a strong technical force. Although Yili has occupied the leading position of domestic dairy products by relying on high technology, it is its own technology and has little to do with the backwardness of Inner Mongolia itself. Finally, B's analysis is the answer. Inner Mongolia has excellent grass quality, developed animal husbandry and good quality of dairy raw materials, so we should learn to use B geography flexibly. I hope I can help you. Thank you.
