Solution

The correct option is C
pachytene

During the pachytene stage of Prophase I, there is an appearance of the recombination nodules where non-sister chromatids of homologous chromosomes cross over. Crossing over is an enzyme-mediated process and the enzyme involved is called recombinase. Crossing over leads to recombination of genetic material on the two chromosomes.
