Select the option figure in which the given figure is embedded as its part (rotation is NOT allowed).

To determine which option figure contains the given given figure as an embedded part without rotation, let us carefully analyze the components of the given figure (Image 0):

1. Structure of the Given Figure:
- Two vertical parallel lines extending top to bottom.
- A horizontal line segment connecting the two vertical parallel lines in the upper middle section.
- A diagonal line segment going from the bottom of the left vertical line up to the horizontal line at the right vertical line.

2. Verification in the Options:
Let us examine Option 3 (Image 3):

- Looking at the middle vertical section of Option 3, we can observe two vertical parallel lines.
- Connected between these two vertical lines at the middle height is a horizontal line segment.
- Starting from the bottom of the left vertical line of this middle section, a diagonal line goes upwards and connects to the right vertical line at the horizontal line's intersection point.
- Thus, the exact given figure is embedded inside Option 3 without any rotation.

Therefore, the correct option is Option 3.
