Solution
The correct option is D prophase of meiosis I The pairing of homologous chromosomes before crossing over is called as Synapsis. It takes place in the prophase 1 of meiosis 1 where subsequently crossing over also takes place in the pachytene phase.
So, the correct option is 'prophase of meiosis I'.
