Meiosis I halves the chromosome number by separating homologous chromosomes into two cells. After this division, each daughter cell contains only one chromosome from each homologous pair, making them haploid with one set of chromosomes. Remember that the chromosomes are still replicated at this point, so each one consists of two sister chromatids, a state that meiosis II will separate. This description fits best because the key change in meiosis I is the reduction from diploid to haploid, not simply maintaining two copies of each chromosome or having four sets.
