Solution
The correct option is B pachytene
Crossing over takes place during the pachytene stage. During this stage, non-sister chromatids of homologous chromosomes may exchange segments over regions of homology. Sex chromosomes, however, are not wholly identical, and only exchange information over a small region of homology. At the sites where exchange happens, chiasmata form. There are no gaps in information formed as a result of the process. Crossing over is also an enzyme-mediated process and the enzyme involved is called recombinase.
