nuclear membrane reforms, cytoplasm divides, 4 daughter cells formed
A
telophase I
B
anaphase II
C
telophase II
D
prophase I
Explanation: 

Detailed explanation-1: -Nuclear membrane reforms, cytoplasm divides. In total 4 haploid daughter cells are formed. Is called “reduction division", because it reduces the number of chromosomes by half. Splits the two chromatids on each chromosome so that each daughter cell has one chromatid per chromosome.

Detailed explanation-2: -Telophase II During the subsequent cell division, the sister chromatids of each chromosome are separated. During telophase II, the sister chromosomes are surrounded by new nuclear membranes.

Detailed explanation-3: -In telophase II, the single-stranded chromosomes uncoil, the spindle apparatus disappears, and the nucleolus and nuclear membrane reform. Cytokinesis occurs and creates two new cells, for a total of four daughter cells formed from the original single parent cell.

Detailed explanation-4: -Telophase II There are now four daughter cells-two from each of the two cells that entered meiosis II-and each daughter cell has half the normal number of chromosomes (Figure 7). Each also contains new mixtures of genes within its chromosomes, thanks to recombination during meiosis I.
