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

The correct option figure in which the given figure is embedded is:

Step-by-step Explanation:
1. Analyze the Given Figure:
First, carefully examine the geometric features, line segments, and intersections of the question figure:

Since rotation is NOT allowed, we must search for the exact shape in this specific orientation.

2. Trace the Shape in the Option Figures:
- Compare the pattern of the question figure against the line arrangements in each option.
- Tracing the segments in the correct option:
reveals the exact unrotated layout of the question figure integrated into its grid-like structure.
- The other option figures fail to contain the complete, uninterrupted set of lines in the correct relative positions.

Thus, the given figure is embedded in the third option figure.
