To solve this, identify the pairs of opposite faces from the unfolded sheet (X). In a standard cube net, faces separated by one face in a row are opposite, and faces attached above/below are opposite to the face they are attached to in the row if they are at the ends of the ‘spine’. Assuming the diagram represents a standard net layout, the most plausible arrangement giving a consistent set of opposite faces is:
Blank
Blank Blank Circle Triangle
Dot
In this configuration (a row of 4 with one above the second/third and one below the fourth/fifth – assuming Circle is the third and Triangle the fourth), the opposite pairs would be:
(Blank, Dot)
(Blank, Blank)
(Circle, Triangle)

In a folded cube, opposite faces cannot be adjacent or visible simultaneously. Let’s check the options against these opposite pairs:
A) Circle, Triangle, Dot. Circle and Triangle are opposite. This cube cannot be formed.
B) Blank, Dot, Triangle. Blank (from the Blank/Blank pair), Dot (from the Blank/Dot pair), and Triangle (from the Circle/Triangle pair). One face from each opposite pair is visible. This cube can be formed.
C) Blank, Circle, Triangle. Circle and Triangle are opposite. This cube cannot be formed.
D) Blank, Blank, Dot. Two Blank faces are visible. For this to be possible, the two visible Blank faces must come from different opposite pairs. One Blank must be from the (Blank, Blank) pair, and the other Blank must be from the (Blank, Dot) pair. However, the Dot is also visible in this option. It is impossible to see the Blank from the (Blank, Dot) pair and the Dot from the same pair simultaneously. Therefore, this cube cannot be formed.

Option B is the only possible cube that can be formed from the given sheet.

In a cube formed from a net, opposite faces are never adjacent and thus cannot be seen in the same view (three-face perspective).
There are 11 standard nets for a cube. Recognizing the type of net helps identify opposite faces quickly. The diagram provided somewhat resembles a standard net despite being slightly ambiguous in exact connections.
