Answer:
B: a secondary source
Explanation:
Information obtained through report and articles by other authors is a secondary source of knowledge:
The secondary sources of information are those that interpret original or primary sources.
For example, in science original research is considered a primary source, it means it was the result of direct observation, or through experimenting with the object of study.
A secondary source would then comment or contrast the findings of the experiment carried on and quote the first source.
While primary sources have not been filtered through interpretation or evaluation by others, secondary sources will refer to the same object, by someone else
In research, a primary source would be a written or spoken record, and secondary sources are generally books, articles,etc. commenting on the matter.
