Select the option figure in which the given figure (X) is embedded (rotation is NOT allowed).

To find the option figure in which the given figure (X) is embedded (without rotation), let us analyze the components of Figure (X):
1. A wave-like curve (sinusoidal wave) starting from the left, going up to a crest, down to a trough, up to a second crest, down to a second trough, and then rising to the right.
2. A vertical line starting near the level of the crests, going straight down through the first trough.
3. A horizontal line extending to the right from the bottom of this vertical line.
4. A second vertical line going straight up from the right end of the horizontal line, ending exactly at the bottom of the second trough.

Now, let us evaluate the given options:
- Option 1: The rectangular loop structure is positioned above the wave and connects at the crests rather than the troughs, which does not match the structure of Figure (X).
- Option 2: This figure consists of stacked oval shapes (pebbles) and two square segments, which does not contain the wave or the path from Figure (X).
- Option 3: Inside the circular frame, we can clearly see the exact wave pattern. A vertical line passes through the first trough, goes downwards, turns horizontally to the right, and then goes vertically upwards to meet the second trough. Although the vertical line on the left extends further upwards to end in a small triangular antenna-like shape, the exact, unrotated shape of Figure (X) is completely embedded within this drawing.
- Option 4: This figure contains jigsaw-like curved segments and a separate square with a circle, which does not contain Figure (X).

Thus, the given figure (X) is embedded in Option 3.
