B

Step 1: Let's analyze each of the column I items one by one and match them with column II items based on the nature of the images produced by different mirrors and lenses.

(i) Convex mirror with Virtual object:
A convex mirror always produces a virtual image, regardless of whether the object is real or virtual. Thus, it matches with [B] Virtual image.

(ii) Concave mirror with Virtual object:
A concave mirror can produce a virtual image when the object is placed between the focal point and the mirror. Thus, it matches with [B] Virtual image.

(iii) Concave lens with Real object:
A concave lens always produces a virtual image, regardless of the object being real. Thus, it matches with [B] Virtual image.

(iv) Convex lens with Real object:
A convex lens can produce either a real or virtual image depending on the position of the object. If the object is located beyond the focal length, it produces a real image, and if it is within the focal length, it produces a virtual image. Therefore, for the case where a real object is used (object located beyond the focal length), it generally produces a diminished image (if the object is between 2F and infinity). Thus, it matches with [D] Diminished image.

Final Matching:
(i) -> (B), (ii) -> (B), (iii) -> (B), (iv) -> (D)

Therefore, the correct answer is: [B].
