Solution
The correct option is B Pachytene
Tetrad formation occurs during pachytene stage wherein the process of crossing over takes place. During this stage, the non-sister chromatids of homologous chromosomes may exchange segments over regions of homology. At the sites where the exchange takes place, the chiasmata is formed. The exchange of segments between the non-sister chromatids results in a recombination of genetic information.Thus, the correct answer is option C.
