The correct Answer is:
To identify the phases of cell division based on the events described, we can analyze each event step by step: ### Step-by-Step Solution: 1. **Event A: Centromere splits, chromatids separate and move to opposite poles, chromatids are now called chromosomes.** - This event describes the process where sister chromatids are pulled apart and move towards opposite poles of the cell. This occurs during **Anaphase**. 2. **Event B: Chromosomes cluster at opposite poles, decondensation of chromosome, reappearance of nuclear membrane, Golgi body (GB), and endoplasmic reticulum (ER).** - In this event, the chromosomes have reached the opposite poles, and the cell is preparing to divide. The nuclear membrane reappears, and the chromosomes begin to decondense. This is characteristic of the **Telophase**. 3. **Event C: Chromosomal replication.** - This event refers to the duplication of chromosomes, which occurs during the **S phase** of Interphase. 4. **Event D: Kinetochores attach to spindle fibers and chromosomes are arranged at the equatorial plate.** - This describes the alignment of chromosomes along the equatorial plane of the cell, which is a key feature of **Metaphase**. 5. **Event E: Condensation of chromosomal materials.** - This event refers to the process where chromatin condenses to form distinct chromosomes. This occurs during **Prophase**. ### Summary of Events and Phases: - **A**: Anaphase - **B**: Telophase - **C**: S phase (Interphase) - **D**: Metaphase - **E**: Prophase ### Final Arrangement: - A → Anaphase - B → Telophase - C → S phase (Interphase) - D → Metaphase - E → Prophase
