A parallel beam of white light is incident on a diffraction grating. Orange light with wavelength $600\ \text{nm}$ in the fourth-order diffraction maximum overlaps with blue light in the fifth-order diffraction maximum. Determine the wavelength of the blue light.
- A$450\ \text{nm}$
- B$480\ \text{nm}$
- C$500\ \text{nm}$
- D$750\ \text{nm}$
