**Category:** Optics  
**Subtype:** Lens and Image Formation  
**Problem Description:** This problem involves a thin lens and the formation of an image of an object (AB) on a screen. The object is a small vertical segment, and the task is to determine the height of the image formed on the screen when the distance between the object and the screen is 7.2 times the focal length of the lens.  

**Key Information:**
- Object height (AB) = 2 cm
- Distance between object and screen = 7.2 * focal length (f)
- The problem requires finding the height of the image of AB on the screen.  

**Options for Image Height:**
A. 10 cm or 0.4 cm  
B. 4 cm or 1 cm  
C. 2 cm or 1 cm  
D. 5 cm or 0.2 cm
