Correct : a

The correct answer is Option A.
In cube folding questions, the approach is to mentally fold the paper net and track which face ends up where. Each face of the net corresponds to one of the 6 faces of the cube - top, bottom, front, back, left, right.
The key rules to remember - opposite faces of a cube never share an edge in the net. Adjacent faces in the net become adjacent faces on the cube. By carefully folding the given net step by step, the face arrangement that results matches Option A.
Options B, C, and D show face combinations or orientations that are geometrically impossible given the net - either they place opposite faces adjacent to each other or show incorrect rotations of specific face markings.
