I. Splitting of centromere
II. Synapsis of homologous chromosome
III. Release of bivalents randomly into cytoplasm
IV. Terminalization of chiasmata

Options

A. I, III, IV, II
B. II, IV, III, I
C. II, III, IV, I
D. II, I, IV,III

Answer

To arrange the events of meiosis in the correct sequence, we need to understand the order in which these events occur during the meiotic process. Here’s the step-by-step breakdown:

1. **Synapsis of Homologous Chromosomes (Step II)**: This is the first event in meiosis where homologous chromosomes pair up. This pairing is crucial for genetic recombination and is characterized by the formation of structures known as bivalents.

2. **Terminalization of Chiasmata (Step IV)**: After synapsis, the homologous chromosomes undergo crossing over at points called chiasmata. Terminalization refers to the movement of these chiasmata towards the ends of the chromosomes, which is an important step before the chromosomes are separated.

3. **Release of Bivalents Randomly into Cytoplasm (Step III)**: Following the terminalization of chiasmata, the bivalents (paired homologous chromosomes) are released into the cytoplasm. This step is part of the transition from metaphase to anaphase.

4. **Splitting of Centromere (Step I)**: Finally, during anaphase, the centromeres of the chromosomes split, allowing the sister chromatids to be pulled apart to opposite poles of the cell. This is the last step in the sequence of meiosis events.

Thus, the correct sequence of events is:
**II → IV → III → I**.

### Final Answer:
The correct order of events is:
**II (Synapsis of homologous chromosomes) → IV (Terminalization of chiasmata) → III (Release of bivalents randomly into cytoplasm) → I (Splitting of centromere)**.
