Solution

The correct option is B Length of chromosomes
Chiasmata is the site of crossing over. This is the location where the exchange of the genetic material between the non-sister chromatids of the homologous chromosomes occurs. Depending on the length of the chromosome, the formation of more than one chiasmata can take place. so, the number of chiasmata depends on the length of the chromosomes.
Thus, the correct answer is option B.
