Show answer and explanation

Correct answer: (A) Option A in the figure

Explanation

Fold each candidate with the marked surfaces on the exterior. The black face, grey face and the face carrying the line must meet around a common corner, with the shown relative orientation.

Option A provides the intended adjacency of these three surfaces. The remaining faces can be blank or marked because they are not visible in the view. **Answer: A.**
