Here's the 
When the `Inherit` constructor is called in the `main` method, the following happens:
1. A `Figure` object `f` is created, and `f.display()` is called. Since `f` is a `Figure`, "Figure" is printed.
2. `f` is then assigned a new `Rectangle` object `r`, and `f.display()` is called again. Since `f` now refers to a `Rectangle`, and `Rectangle` overrides the `display()` method, "Rectangle" is printed.
3. Finally, `f` is assigned a new `Box` object `b`, and `f.display()` is called once more. Since `f` now refers to a `Box`, and `Box` also overrides the `display()` method, "Box" is printed.
Therefore, the output is:
```
Figure
Rectangle
Box
```
This corresponds to option A) FigureRectangleBox.
