I think you're answering a different question, something more like "What can be inferred about the test case strategy?"
(E) it had subjective aspects to it
The crucial wording in the question stem is the author views the test case strategy as ...
That should transform your thinking into, "how did the author feel about the test case strategy?" or "what did the author think was important/noteworthy about the test case strategy?"
Either way, the proof sentence we'll use to support our answer needs to be one that conveys the author's attitude. The line reference you were alluding to that itemizes some of the factors considered in how Marshall chose his clients is purely factual.
So while it's true to say that Marshall made some subjective assessments in choosing his clients, there is no sentence in the passage that conveys the author's attitude about Marshall's subjectivity.
Instead, we're getting (C) as the credited response because this best reinforces the author's overall attitude in this passage toward Marshall's innovations.
Line 13-15 is the author's "Main Headline" for this passage. Lines 59-62 but the final stamp on that legacy while cementing our support for (C) with "the techniques that he honed - originally considered to be a radical departure from accepted conventions".
I will grant you that the above wording does not actually prove the strength of 'unprecedented' ... also, lines 27-30 do somewhat support (E) in terms of expressing author attitude that "choosing the right plaintiff" was crucial.
But again, if we surmise that this question is fishing for the big picture author attitude toward Marshall's test case strategy, we want to pick the answer that reinforces the most important author ideas in the passage.
Finally, 'arbitrary' and 'subjective' are a little too close for comfort to me, in meaning. When we label something 'arbitrary', we're implying that it was done according to someone's whim (subjective) rather than according to merit/rule/objective reasons.
Generally, if two answers are saying almost the same thing, they cancel each other out.
Hope this helps.
