In Donne's sonnet, the phrase "one short sleep past" means: Death, like a nap, isn't permanent. I can assure that option D is correct.
In fact, the lines after that mentioned in the questions are: we wake eternally
And death shall be no more; Death, thou shalt die.
Which confirms that for the author, the death is not permanent or eternal, on the contray, life is, so we will wake eternal and death would die.
