* is reflexive but not transitive and symmetric
B.
* is transitive but not reflexive and symmetric
C.
* is symmetric and reflexive but not transitive
D.
* is neither reflexive, nor symmetric, nor transitive
If \( z = x + iy = \left(\frac{1}{\sqrt{2}} - \frac{i}{\sqrt{2}}\right)^{-25} \), where \( i = \sqrt{-1} \), then what is the fundamental amplitude of \( \frac{z - \sqrt{2}}{z - i\sqrt{2}} \)?
