(C) "symmetry"
When the planetarium display reveals that Mercury's orbit is more difficult than previously believed, the narrator is dismayed. Contrary to the antiquated notion that Mercury rotates simply once every solar orbit, it appears that the moonless planet rotates three times per two trips around the sun. The narrator seems to favor "symmetry," or balance, by favoring the more straightforward "arrangement."
The answer is not (A). Lines 40–43 don't show any "irony" on the part of the narrator. (B) is the wrong answer. Though unconventional, the narrator's response to Mercury's "strange arrangement" does not truly show "inventiveness" or ingenuity. The answer is not (D). The passage's narrator gives a lot of facts, yet he does it in an understandable way.
Therefore, it is a little misleading to say that the narrator's manner in lines 40–43 is decorative or ornamented. The answer is not (E). Regarding Mercury's complex orbit, the narrator seems to dislike "ambiguity" or confusion rather than enjoy it.
