C. II and III only

D. I, II, and III

Solution

As per the diagram line m is the y=x line in the cartesian coordinate system so as per the reflection rule the coordinates of preimage and image will be as exchange of x,y values,So by that triangle 2 is reflection of traingle 1

As per the figure line l is y axis line so the value of y will be constant and x value will be -(x) value ,so as per the reflection rule preimage and image coordinates will be(x,y),(-x,y) therfore in accordance with line l triangle2 is reflection of triangle 3

therefore option B I and III only(Rl (triangle 3) and Rm(traingle 1))
