Thin lenses questions

During an experiment, a thin-lens system in its initial state produces a real, inverted, and enlarged image and in its final state produces a virtual, upright, and enlarged image. Which of the following statements best elucidates on what kind of change occurred for the thin-lens system?

(Choice A)
The object is moved from a point outside the radius of curvature to a point within the focal length of a concave lens.
(Choice B)
The converging lens is swapped for a diverging lens to create the switch in orientation.
(Choice C)
The object is moved from a point outside the focal length to a point within the focal length of a convex lens.
(Choice D)
An additional converging lens was placed outside the focal point of the original lens.
