The correct sequence of events in prophase $I$ is

• A
  Synapsis $\rightarrow$ Crossing over $\rightarrow$ Chiasmata $\rightarrow$ Terminalisation
• B
  Crossing over $\rightarrow$ Synapsis $\rightarrow$ Chiasmata $\rightarrow$ Terminalisation
• C
  Chiasmata $\rightarrow$ Synapsis $\rightarrow$ Crossing over $\rightarrow$ Terminalisation
• D
  Chiasmata $\rightarrow$ Crossing over $\rightarrow$ Synapsis $\rightarrow$ Terminalisation
