The apparent discrepancy in the fact pattern is the question of why dissenting judges write with high literary quality writing when such writing is more likely to be misunderstood than is less high literary writing. This is strange especially because judicial decisions themselves tend to avoid high literary writing, since they are intended as determinations of law.
We should look for the answer that addresses the dissenting judges’ style choice head on:
(A) could be tempting, but only if we make some sort of additional assumption about what impact multiple writers have on the writing style of an opinion. Regardless, it doesn't help explain the different between the decisions and dissenting opinions.
(B) applies equally to the official opinion and the dissenting opinion, so it does not explain why only dissenting judges seem to opt for the less clear writing style.
(C) is helpful because it indicates a difference between the judicial decision and the dissenting opinion. And it indicates a good reason why dissenting judges might be less likely to worry about ambiguity/etc than the authors of the decision in a case.
(D) has the same problem as (B).
(E) has the same problem as (B) and (D).
So (C) is our answer.
