Solution

The correct option is C chiasmata
Chiasmata is the region of crossing over between two homologous chromosomes during Propase I of meiosis.
Centrosomes are key to the division of cells and produce the spindle fibers that are required during metaphase of mitosis. Each centrosome consists of two centrioles that are orientated at right-angles to each other. Centromere is the part of a chromosome. The kinetochore forms in eukaryotes, assembles on the centromere and links the chromosome to microtubule polymers from the mitotic spindle during mitosis and meiosis.
