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

The correct option is:

Step-by-step breakdown:

1. Analyze the Given Figure (X):
Figure (X) consists of a horizontal cylindrical/tunnel-like shape intersecting with a triangle on its left side:
- A triangle with a flat base.
- A horizontal cylindrical shape extending to the right with an elliptical face at its right-hand end.
- A left curved arc representing the left edge of the cylinder intersecting the triangle's left leg.
- Horizontal lines extending from the top curve of the cylinder to the right ellipse.

2. Search for Figure (X) within the Options (Without Rotation):
- By inspecting the fourth option, we can see the exact features of Figure (X) embedded inside a rectangular outer frame on the left side:
• The triangle is present inside the rectangle.
• The horizontal cylinder with its left curved boundary intersecting the triangle and its right elliptical end is completely intact in the exact same orientation without any rotation.

Therefore, Figure (X) is embedded in the fourth option image.
