Solution

The correct option is D C → B → E → A → D
Synapsis happens in the second stage or zygotene of prophase I.

Crossing over happens in the third stage or pachytene of prophase I.

The beginning of diplotene is recognized by the dissolution of the synaptonemal complex and the tendency of the recombined homologous chromosomes of the bivalents to separate from each other except at the sites of crossovers.

The final stage of meiotic prophase I is diakinesis. This is marked by terminalisation of chiasmata.

Disjunction is the separation or moving apart of chromosomes towards opposite poles of the cell during cell division. Disjunction normally occurs during the anaphase of mitosis and meiosis (I and II).
