There is a little problem with your question, in the file, the question is about metaphase, and here you talk about anaphase.
The right answer is D if it is metaphase, and A if it is anaphase.
The good description of the metaphase is the proposition D. Indeed it is an organization of the chromosomes in the equatorial plate (in the middle of the cell).
The anaphase corresponds rather to the answer A. It is a separation of the sister chromatids of each chromosome which was retained by the kinetochores.
