Explanation:

To determine the meiosis I stage, we analyze the illustration:

• Prophase I: Involves synapsis and crossing over; chromosomes are condensing, not at the stage of cell division shown.
• Telophase I: The cell is dividing into two, with chromosomes at the poles and nuclear envelopes reforming. The illustration shows two cells forming (cytokinesis starting) with chromosomes still visible in each new cell, consistent with Telophase I (where the first meiotic division ends, producing two haploid cells with duplicated chromosomes).
• Metaphase I: Chromosomes line up at the equator in tetrads; the illustration does not show this alignment.
• Anaphase I: Homologous chromosomes separate; the illustration does not show chromosome movement to opposite poles.

Answer:

B. Telophase I (Note: Assuming the options are labeled as A. Prophase I, B. Telophase I, C. Metaphase I, D. Anaphase I; the correct option is the one for Telophase I.)
