Step 1: For a concave mirror with a real object, when the object is placed beyond the center of curvature (C), a real image is formed on the same side as the object, which is inverted and can be captured on a screen. Hence, (i) matches with [A] Real image.

Step 2: A convex mirror always forms a virtual image irrespective of the position of the object, which is upright and reduced in size. Therefore, (ii) corresponds with [B] virtual image.

Step 3: A concave lens always produces a virtual image that is erect and diminished when a real object is positioned in front of it. Thus, (iii) matches with [B] virtual image. However, since an option is required for real objects, this can also correspond with [D] diminished image if we contextualize it. In this interpretation, (iii) could correlate with [D] diminished image.

Step 4: For a convex lens with a real object placed beyond the focal point, it forms a real image which can either be diminished or magnified depending on the object's location (above the focal length for magnification and below for diminished). As typically stated in many contexts, the general case given in problems often leads us to consider a real image formation as diminishing when referenced to projection screens. Therefore, (iv) correlates with [D] diminished image.

Final matching results from the analysis:
(i) -> [A]
(ii) -> [B]
(iii) -> [E]
(iv) -> [D].
Therefore, the final summation of matches should regard (iii) to reinterpret for diminished under common lens conventions. Hence, we state the more general measurable patterns.
