A student is shown a photomicrograph of a cell organelle. The magnification of the photomicrograph is known. Which calculation gives the true length of the organelle in $\mu\text{m}$?
- Aactual size in $\text{cm} \times 100$ divided by the magnification
- Bactual size in $\text{mm} \times 100$ divided by the magnification
- Cimage size in $\text{cm} \times 1000$ divided by the magnification
- Dimage size in $\text{mm} \times 1000$ divided by the magnification
