Question
**Question 23** The image contains six diagrams labeled I to VI, representing different stages of chromosome arrangement during cell division, either mitosis or meiosis. **Diagram I**: Two pairs of sister chromatids are connected at the centromere, aligned at the metaphase plate with spindle fibers attached at the centromeres. **Diagram II**: Similar arrangement as Diagram I, but the chromatids appear to be pulled slightly apart toward opposite poles by the spindle fibers. **Diagram III**: Two separate X-shaped structures without any spindle fibers, indicating separate chromatids or chromosomes. **Diagram IV**: Two sets of entangled chromatid arms, suggesting chromosomal crossing over or synapsis, possibly during prophase I of meiosis. **Diagram V**: The chromatids are aligned at the metaphase plate, similar to Diagram I, but the arrangement appears slightly altered, indicative of another metaphase stage. **Diagram VI**: The chromatids are at the poles, indicating separation, with spindle fibers appearing to guide them to opposite ends, suggesting anaphase or telophase. **Figure 10.2**: Refer to the drawings in Figure 10.2 of a single pair of homologous chromosomes as they might appear during various stages of either mitosis or meiosis. Which diagram represents anaphase I of meiosis I? - a. I - b. II - c. IV - d. V
