Following statements are regarding to model for reassembly of the nuclear envelope during telophase. 
A. Extensions of the endoplasmic reticulum (ER) associate with each decondensing chromosome and then fuse with one another, forming a double membrane around the chromosome. 
B. Dephosphorylated nuclear pore subcomplexes reassemble into nuclear pores, forming individual mini-nuclei called karyomeres. 
C. The enclosed chromosome further decondenses, and subsequent fusion of the nuclear envelopes of all the karyomeres at each spindle pole forms a single nucleus containing a full set of chromosomes.
D. Phosphorylated nuclear pore subcomplexes reassemble into nuclear pores, forming individual mini-nuclei called karyomeres.
