Find the solution set of the equation

x^{3} - 8 i = 0

in the set of complex numbers.

{\sqrt{3} + i; - \sqrt{3} + i; - 2 i}

{2 i; - \sqrt{3} - i; \sqrt{3} - i}

{\frac{\sqrt{3}}{2} + \frac{1}{2} i; - \frac{\sqrt{3}}{2} + \frac{1}{2} i; - i}

{i; - \frac{\sqrt{3}}{2} - \frac{1}{2} i; \frac{\sqrt{3}}{2} - \frac{1}{2} i}
