Correct answer: D
Correct answer: 6
Key idea: Fold the net mentally and identify opposite faces, not just neighbouring squares in the flat image.
The face with 6 dots is two squares above the face with 3 dots in the vertical strip. When folded through the 1-dot face, the 6-dot face comes directly opposite the 3-dot face.
The 4-dot face shares an edge with the 3-dot face, so it is adjacent. The 2-dot and 5-dot faces fold around the side strip and are not opposite to the 3-dot face.
Therefore, the face opposite the face having 3 dots has 6 dots.
