Dear Student,
The correct option is option B.
Mitosis consists of 2 major events: Karyokinesis and Cytokinesis.
Karyokinesis consists of 4 stages: Prophase, Metaphase, Anaphase and Telophase.
1. Prophase: Chromatin condenses to form chromosomes. Initiation of mitotic spindle occurs. Golgi complex, ER, nuclear membrane and nucleolus disintegrate.
2. Metaphase: Chromosomes spread throughtout the cytoplasm. Chromosomes contain 2 chromatids attached to each other through the centromere. Mitotic spindle formation is completed. All chromosomes align themselves at equator. Spindle fibers attach to kinetochore.
3. Anaphase: Centromere which holds the chromatids together splits and daughter chromatids are now called chromosomes of future daughter nuclei. Chromosomes move away from equatorial plate.
4. Telophase: Chromosomes reach poles. Mitotic spindle disappears. After reaching poles, chromosomes uncoil. Nucleolus, ER, Golgi bodies and other organelles reappear. Nuclear envelope reappears.
Hope this helps in clearing your doubts.
Regards
