Answer:
The right option for this case is option "C" i.e. between focus i.e. "F" and optical center i.e. "O".
Explanation:
The third option best represents the case, as the closer an object is brought by a person towards a lens, the resultant effect is such that, the size of the image keeps on increasing.
This is further continued as a person brings the object more closer as compared to the previous respect.
So, when an image is placed between a focus or focal point and between the optical center, the resultant image is on the same side as that of the object, and it is virtual, enlarged and erect in nature and shape.
