The correct answer is Primary source
Explanation:
Sources including written documents, photographs, records and any type of material with information are usually classified as primary or secondary. A source is considered as primary when it is a first-hand account of the event being studied which means a primary source is a source written by someone who experienced or witnessed the events he or she described in the source and therefore the source directly record these events. On the other hand, a source is a secondary source when it uses primary sources and summarize them or analyze them, which means the author did not witness or experience the event but uses the information of record by others to create a new document.
Considering the previous ideas, in the case of a historian who found a diary that belongs to an Indian princess this source can be classified as a primary source because the author of it (the Indian princess) directly recorded events that she witnessed (information about the women of her dynasty) and therefore this document works a first-hand account of events or primary sources. Thus, the princess's diary is a primary source.
