A) \[|{{z}_{1}}+{{z}_{2}}|=|{{z}_{1}}|+|{{z}_{2}}|\]
B) \[|{{z}_{1}}-{{z}_{2}}|=|{{z}_{1}}|-|{{z}_{2}}|\]
C) \[|{{z}_{1}}-{{z}_{2}}|\le |{{z}_{1}}|+|{{z}_{2}}|\]
D) \[|{{z}_{1}}-{{z}_{2}}|\le |{{z}_{1}}|-|{{z}_{2}}|\]
E) \[\left| \frac{{{z}_{1}}}{{{z}_{2}}} \right|\ne \left| \frac{{{z}_{1}}}{{{z}_{2}}} \right|,\]where\[{{z}_{2}}\ne 0\]
