Answer: B
Explanation: As per the question, the author's identification stage would be characterized as the examination of the 'origin' of the source. Identification of the author is the elemental stage which could further assist in assessment of his/her purpose of the text along with the biases involved(if any) or the agenda behind the creation. These together would contribute to an effective examination of the source and aid in taking significant decisions(whether to rely upon, how to use the information, etc.). Thus, option B is the correct answer.
