Solution

The correct option is B Diakinesis
In meiosis, nuclear membrane and nucleolus disappear during diakinesis which is the final stage of the prophase in meiosis, characterized by shortening and thickening of the paired chromosomes, the formation of the spindle fibers, disappearance of the nucleolus, and degeneration of the nuclear membrane.
So, the correct answer is 'Diakinesis'.
