Show answer and explanation
Correct answer: (B) Only (ii)
Explanation
Track face identities while folding: the L-shaded face and quarter-shaded face are opposite, as are the triangular face and the first striped face; the center and last half-shaded face are opposite. Then preserve the orientation of each shaded corner along shared edges. Cube (ii) matches these face and corner relationships. In (i), the L-shaped shading is reversed relative to the adjacent triangular shading, so a rotation cannot produce it. **Only (ii), B**.
