Interpret the following locii in \( \mathrm{z} \in \mathrm{C} .1|\mathrm{z}-2 \mathrm{i}|3 \)
(a) Region between the concentric circles with centre \( (0 \), 2) and radii 1 and 3
(b) region outside or on the circle centre \( (1 / 2,2) \) and radius \( =1 / 2 \)
(c) semicircle in I and IV quadrants, \( x^{2}+y^{2}=1 \)
(d) a ray emanating from the point.
