    A recondite, ponderous Correct Answer Incorrect Answer
    B arcane, oblivious Correct Answer Incorrect Answer
    C esoteric, preoccupied Correct Answer Incorrect Answer
    D cryptic, distance Correct Answer Incorrect Answer
    E esoteric, unaffected Correct Answer Incorrect Answer

    Solution

    "Arcane" perfectly fits the context, referring to something known or understood by only a few, and "oblivious" fits well because the physicist is so absorbed that he is unaware of anything else. Thus, the best answer is (b) arcane, oblivious.
