Solution

The correct option is A Chiasmata
The chiasmata is the X-shaped structure which is formed when the recombined homologous chromosomes separate from each other except at the sites of crossover. It is seen during the diplotene stage of prophase I of meiosis I.

During the zygotene stage of prophase I of meiosis I, the homologous chromosomes begin to pair up by a process called synapsis. The synapsed homologous chromosomes are called bivalents or tetrads. This is also associated with the formation of the synaptonemal complex.
