D.
Investigate the main idea of the resource you discover.

Correct answer is A.  Determine the resource's original medium of production.

Explanation:

A is correct answer because it is important to know how reliable the source - is it forged or not, and its validity - to see if the information contained there are true.

B is wrong because it is not important who the author is, but is he reliable enough.

C is wrong because it doesn't matter how many time the resource has been published, if it is not reliable.
