This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is

To solve this problem, we need to determine how the given shape will form a cube when folded. Let's analyze the given sheet and the options.

The provided sheet is a net of a cube. When folded, each face will align to form a cube:

  1. Identify Opposite Faces: In a cube, each pair of opposite faces are not visible at the same time. By visually inspecting the net:
    • Face 1 is opposite to Face 4.
    • Face 2 is opposite to Face 6.
    • Face 3 is opposite to Face 5.
  2. Determine Adjacent Faces: Faces that are not opposite are adjacent.
    • Face 1 is adjacent to Faces 2, 6, and 5.
  3. Fold the Net: Visualize the folding:
    • Face 1 becomes the base.
    • Face 2 and 6 fold up to form sides.
    • Faces 5 and 3 form the remaining sides, with Face 4 on top.

Now, let's compare this with the options provided to identify the correct cube. The correct cube will have opposite faces as determined and correctly aligned adjacent faces. The final option matches this description:

Thus, the correct answer is the cube shown in the last image above. This configuration satisfies the conditions of opposite and adjacent faces.
