The photographs display an eyepiece graticule and a stage micrometer scale as seen under a microscope. The tiniest intervals on the stage micrometer scale are $0.01\,\text{mm}$. The photographs also present a photomicrograph of a transverse section through a plant root, taken with the same eyepiece graticule and at the same magnification. What is the true width of the vascular tissue in the plant root from X to Y?
- A$17\,\mu\text{m}$
- B$25\,\mu\text{m}$
- C$170\,\mu\text{m}$
- D$250\,\mu\text{m}$
