The statements A. A chromosome is the thickest during the metaphase and B. A chromosome is the shortest during the metaphase are true about the metaphase.
The metaphase stage of cell division can be defined as the second stage after prophase in which condensed chromosomes are located at the equatorial plate of the cell in order to match with their homologous chromosomes and correctly segregate during the next stage, i.e. the anaphase stage.
During the metaphase stage of cell division, the chromosomes are in this maximum condensation stage and therefore they are shorter and thickest when compared to other stages of the cell cycle.
Therefore, with this data, we can see that the metaphase stage of cell division is the phase in which chromosomes are located at the equatorial plate and are condensed.
