text: D. Complex numbers cannot be ordered as they have both size and direction\n\nTheir moduli can be ranked\n|5 - i| > |3 - 2i| \n\nand their directions can be given\narg (3 - 2i) = arctan (-2/3) and arg (5 - i) = arctan (-1/5) \n\nBut you can draw no such ordering conclusions about these two complex numbers
