To arrange the events of meiosis in the correct sequence, we need to follow the steps:

1. Synapsis (b): This is the first step where homologous chromosomes pair up and form a structure called a synaptonemal complex.

2. Crossing over (a): During this step, genetic material is exchanged between the paired homologous chromosomes, resulting in genetic recombination.

3. Terminalisation of Chiasmata (c): Chiasmata are the points where the homologous chromosomes are still connected after crossing over. Terminalisation refers to the separation of these connections.

4. Disappearance of nucleolus (d): The nucleolus, which is responsible for the production of ribosomes, disappears during meiosis.

Therefore, the correct sequence of events in meiosis is: b → a → c → d.
