(B) Prophase $I$ of meiosis is divided into five sub-stages: Leptotene,Zygotene,Pachytene,Diplotene,and Diakinesis.$1$. During Zygotene,homologous chromosomes pair up,a process known as synapsis.$2$. When synapsis is complete,the cell enters the Pachytene stage.$3$. In the Pachytene stage,the bivalent chromosomes clearly appear as tetrads,and crossing over (exchange of genetic material between non-sister chromatids of homologous chromosomes) occurs.$4$. Therefore,the stage described is Pachytene.

When synapsis is complete all along the chromosome,the cells are said to have entered a stage of prophase $I$,where exchange of genetic material takes place between homologous chromosomes. The stage is called
