Answer:
The correct answer would be C. telophase I.
Telophase is the last stage of meiosis I.
In this stage, homologous chromosomes are separated from each other which results in the formation of two daughter cells from a single parent cell.
In addition, each daughter cell contains half the chromosome of the parent cell.
In contrast, in telophase II, sister chromatids are separated.
It can easily be observed that the homologous chromosomes are separated in which sister chromatids are still joined together.
Thus, the given diagram is of the telophase I.
