Solution
The correct option is B Zygotene
Prophase I of meiosis is a long and complex process comprising of leptotene, zygotene, pachytene, diplotene and diakinesis. The zygotene stage, also known as zygonema, occurs as the chromosomes approximately line up with each other into homologous chromosome pairs. Zygotene stage is characterised by pairing of homologous chromosomes. This is essential for subsequent crossing over which occurs during pachytene stage.
