- Bpachytene
- Cdiplotene

Correct answer
B. pachytene
Step-by-step solution
The synapsis, pairing of homologous chromosomes takes place during zygotene. Synapsis results in the formation of bivalents during zygotene. The formation of special proteinaceous structure called synaptonemal complex occur. After zygotene stage cell entered in pachytene stage in which the bivalents become spiralled, shortened and thickened.
