Fundamentals

The image produced by a converging lens has characteristics that are dependent upon the location of the object. The general Location, the Orientation (upright or inverted), the relative Size (smaller, larger, or the same size as the object), and the Type (real or virtual) will all be affected by the location of the object.

There are two similar versions of this question. Here is one of those versions:
 

Version 1:
The red arrow represents an object located two focal lengths from a converging lens. Identify the characteristics of the image that is produced -– location, orientation, size and type.

 

How to Think About This Situation:

The given diagram shows the object located at the 2F point of a convergin lens. When the object is located here, the image that is produced will always be located on the opposite side of the lens at the 2F point; it will be inverted; it will be the same size as the object; and it will be a real image. The image that you pick must have these characteristics.
