Find out which of the figures can be formed from the pieces given in the first fig

ure (X).

Let's analyze the components provided in figure (X):
1. A small quadrilateral with one curved side (top-right).
2. A small triangle (top-left).
3. A large trapezoid/quadrilateral (bottom-left).
4. A small U-shaped or open quadrilateral (bottom-right).

Let's look at the answer options to find where these four pieces are combined:

* Option A features a circle intersecting lines, which doesn't match the straight and slightly curved geometric boundaries of figure (X).
* Option B shows a closed combination at the bottom, but the upper area is empty.
* Option C perfectly assembles all the components: the large base quadrilateral on the left, the curved upper piece, and the remaining segments forming a harmonious closed outer square box.

Therefore, the correct figure that can be assembled from the given pieces is C.
