Let`z`,`z_0`be two complex numbers `z_0`being the cojugate of `z_0`. The numbers `z`, `z_0`, `zbar z_0`,1 and 0 are represented in argand diagram by `P`,`P_0`, Q, A and origin respectively. If `|z|=1`, then (A) `triangle POP_0` and `triangle AOQ` are congruent (B) `|z-z_0| = |zbarz_0 -1|` (C) `|z-z_0| = 1/2|zbarz_0 -1|` (D)none of these

A
