An optical image is formed due to intersection of reflected rays when reflected rays actually meet,the image so formed is called real.when reflected ray apper to meet,than image formed is called virtual.There are three plane mirrors arranged perpendicular to each forming principal co-ordinate planes namely x-y,z-y and z-x.Their common point of intersection is taken as origin.A point object having co-ordinate (1,2,3)is placed as shown in fig
Which of the following is not the coordinates of images formed due to meeting of rays undergoing single reflection only
(a) (1,2,-3)
(b)(1,-2,3)
(c)(-1,2,3)
(d)none
