The best choice here for analyzing connections within a text is:
B. How is this text organized?
Choices A, C and D would not necessarily help identify connections being drawn between ideas in the text. Analyzing the organization and structure of ideas can help reveal how the author is constructing logical connections and building an argument or narrative. The credibility of the evidence, other works by the author, or the opinions themselves would not directly help with identifying connections.
So the best choice is B: How is this text organized?
