Which of the following options gives the correct sequence of events during mitosis?
- ACondensation → nuclear membrane disassembly → crossing over → segregation → telophase
- BCondensation → nuclear membrane disassembly → arrangement at equator → centromere division → segregation → telophase
- CCondensation → crossing over → nuclear membrane disassembly → segregation → telophase
- DCondensation → arrangement at equator → centromere division → segregation → telophase

The correct sequence is:
Condensation of chromatin into chromosomes (Prophase).
Disassembly of nuclear membrane (Late Prophase).
Arrangement at equator (Metaphase).
Centromere division and segregation of sister chromatids (Anaphase).
Telophase.
Note: Crossing over occurs in Meiosis, not Mitosis.
