Solution

The correct option is A Diakinesis
The chromosomes appear thick and short and located near the periphery of the nucleus during diakinesis. This is the first point in meiosis where the four parts of the tetrads are actually visible. The sites of crossing over entangles together effectively overlap and make chiasmata clearly visible.
So, the correct answer is option A.
