Which of the given numbers does not belong to the solution set of the following equation?
\[x^{4}-1+\mathrm{i}=0\]
\(\root{8}\of{2}\left (\cos \frac{3\pi}{16} + \mathrm{i}\sin \frac{3\pi}{16}\right )\)
\(-\root{4}\of{1-\mathrm{i}}\)
\(-\mathrm{i}\root{4}\of{1-\mathrm{i}}\)
\(\root{8}\of{2}\left (\cos \left(-\frac{\pi}{16}\right) + \mathrm{i}\sin \left(-\frac{\pi}{16}\right)\right )\)
