Answer 2

Prometaphase

Explanation:

• The karyokinesis also called as mitosis. It is the first phase of the mitosis phase in which the division of the nucleus of the cell takes place.
• In prometaphase the fragments of the nuclear envelop starts to degenerate and the nuclear envelop begins to disappear so that the nucleus can be divided into daughter nuclei.

• The chromosome becomes more condensed in the stage.

• Each sister chromotid develops a structure called as kinetochore which attracts and binds to the microtubules.
