E Correct answer
Explanation

The chromosomes continue to pull apart, but non-sister chromatids are still loosely associated via the chiasma. The chiasma begins to move toward the ends of the tetrad as separation continues. This process is known as terminalisation. Also during diakinesis, the nuclear envelope breaks down and the spindle fibers begin to interact with the tetrad.
