Which of the following best explains why there different interpretations about historical events

Hey You!

I'd say the answer should be B- they are written by people having differing values and views. 

That is a sensible reason. 

I wouldn't be choice A. That isn't a goal of historians. 
It wouldn't be C. Primary sources would be easy to get a hold of. (that's why their consider primary)

If I had to choose one, I would say B. It conveys and answers the question better.

If you need more help, ask me.

Brainliest answer is always appreciated.
