Which phase of mitosis is shown in the diagram

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase.
In early prophase, the cell starts to break down some structures and build others up, setting the stage for division of the chromosomes.
In late prophase (sometimes also called prometaphase), the mitotic spindle begins to capture and organize the chromosomes.
In metaphase, the spindle has captured all the chromosomes and lined them up at the middle of the cell, ready to divide.
In anaphase, the sister chromatids separate from each other and are pulled towards opposite ends of the cell.
In telophase, the cell is nearly done dividing, and it starts to re-establish its normal structures as cytokinesis (division of the cell contents) takes place.
Cytokinesis, the division of the cytoplasm to form two new cells, overlaps with the final stages of mitosis. It may start in either anaphase or telophase, depending on the cell, and finishes shortly after telophase.
