The diagram presents a stage micrometer scale as seen through an eyepiece fitted with a graticule. Each minor division on the stage micrometer scale measures $0.1\ \text{mm}$. The stage micrometer scale is then substituted with a slide of a plant cell. What is the maximum actual length of the nucleus in the plant cell?
- A$8\ \mu\text{m}$
- B$25\ \mu\text{m}$
- C$200\ \mu\text{m}$
- D$0.8\ \text{mm}$
