Explanation
Something lasting a millionth of a billionth of a billionth of a second is “very shortlived.” Ephemeral and fleeting have just this meaning. In real life, the particles may be small (infinitesimal), there may be a lot of them (myriad, countless), and they may bring a tear to the eye of a few scientists (poignant), but none of these are indicated by clues in the sentence.
Hence options ephemeral, fleeting are best fit!
