E)The homologous chromosomes are now in the haploid or n condition.

In the G₂ phase, DNA replication occurs and results in the formation of two identical copies of each chromosome called sister chromatids. Therefore, the homologous chromosomes have all been copied through DNA replication and are now sister chromatids. This phase is also known as the S phase, where DNA synthesis occurs. The homologous chromosomes are not lined up on the equator or pulled to their respective poles during this phase. Additionally, the cell is still diploid or 2n, not haploid or n, which means it has two sets of chromosomes.
