Solution
The correct option is B Zygotene
In zygotene, the homologous chromosomes come to lie side by side and get attached laterally due to the development of nucleoprotein between them. Pairing is such that the genes of the same character present on the two chromosomes come to lie exactly opposite. This pairing of homologous chromosomes is called as synapsis or syndesis.
