(d) Nuclear envelope starts to disintegrate

I have been asked this question by my college director while I was bunking the class.

I would like to ask this question from Cell Cycle and Division in portion Cell Cycle and Cell Division of Biology – Class 11

The correct answer is (d) Nuclear envelope starts to disintegrate

To elaborate: During metaphase, the nuclear envelope has completely disintegrated. The chromosomes spread out throughout the cytosol and the chromosomes lie at the equatorial plane, attached to spindle fibers.
