She plots a graph between the image distance v and the object distance u as shown in the given figure.
In column I, nature of the mirror/lens is given and in column II the numbers corresponding to the curves on the graph are given. Match column I with column II and select the correct option from the given codes.

Column I Column II
(p) Converging mirror (i) 1
(q) Diverging mirror (ii) 2
(r) Converging lens (iii) 3
(s) Diverging lens

Ap-(i); q-(ii); r-(i); s-(iii)
Bp-(iii); q-(ii); r-(ii); s-(iii)
Cp-(ii); q-(i); r-(i); s-(ii)
Dp-(i); q-(ii); r-(i); s-(ii)
