    E No improvement Correct Answer Incorrect Answer

    Solution

    The idiom "came out of the blue" means something happening unexpectedly or as a surprise, which does not fit the context of the sentence. The sentence suggests that the scientist was initially dismissed but was later proven right, which means he ultimately had the last laugh—an idiom that means gaining success or proving others wrong after being doubted or mocked.Thus, "had the last laugh" is the most appropriate replacement.
