this diagram shows cytokinesis. which diagram shows the phase right before cytokinesis?

Brief Explanations:

Cytokinesis follows mitosis. The phase right before cytokinesis is the end - stage of mitosis. In mitosis, the last stage is telophase where the chromosomes have reached the opposite poles and the nuclear envelope starts to reform. The diagram showing the cell with two distinct nuclei forming at opposite ends of the cell, which is the second diagram in the bottom - row options, represents the phase right before cytokinesis as it indicates the end of nuclear division and is ready for the physical separation of the cell into two daughter cells.

Answer:

The second diagram in the bottom - row of options.
