( A ) condensation → nuclear membrane disassembly → crossing over → segregation → telophase
( B ) condensation → nuclear membrance disassembly → arrangement at equator → centromere division → segregation → telophase
( C ) condensation → arrangement at equator → centromere division → segregation → telophase
( D ) condensation → crossing over → nuclear membrane disassembly → segregation → telophase
