C

To match the arrangements in Column I with the number of images formed in Column II, we analyze the type of lens and the arrangement of the object:
1. **(i)** The first arrangement represents a concave lens with a single object placed at a distance greater than its focal length, producing **1 virtual image** (option [A]).
2. **(ii)** The second arrangement shows a convex lens with the object placed at a distance less than the focal length, resulting in **2 real images** (option [B]) because it forms a real image on the opposite side and a virtual one on the same side when displaced.
3. **(iii)** The third arrangement is likely a converging lens or concave mirror that can produce **3 images**. This typically occurs in certain configurations when multiple reflections are involved (option [C]).
4. **(iv)** For the last arrangement, if it involves a convex lens and an object placed further away or in a specific configuration, it can create **4 images** (option [D]). Thus, pairing the arrangement with images:
(i) - [A]; (ii) - [B]; (iii) - [C]; (iv) - [D].
Therefore, the correct matches are: (i) - [A]; (ii) - [B]; (iii) - [C]; (iv) - [D]. Hence, the answer is C.
