The correct answer is C) Citations.
A citation is when an author gives credit to an individual for a quote, picture, or some other type of information. Reliable sources include citations because it allows the reader to look into the sources the author used in order to create their book. If the person looks into the resources used and they are not from accredited or peer reviewed works, it will discredit the author's argument.
This is especially true in the field of history. The most reliable sources are ones that contain several citations and have been peer reviewed by other professionals within the same field.
The Mongols were an empire that succeded in preservating their culture and their ways thanks to the comercial spirit they had.

They were a culture opened in the sense that everyone could chose what to believe and how to live, this was a way of showing Asia how they lived and inspiring millions of people to be part of the culture.
This characteristic has made the mongols remain as a culture and it continues the enlargement of their followers.
