The correct option is D 5
Choose any 2 dice that have only one number in common.
For example, figures 1 and 2 have only 5 in common.
Now, move clockwise as per the dice.
Figure 1: 5–3–6 (3 and 6 are adjacent)
Figure 1: 5–2–4 (2 and 4 are adjacent)
Hence, 3, 6, 2, and 4 are adjacent to the number 1.
We can observe that 3 is only opposite 2, and 6 is opposite 4.
Now, only 5 is left, which is opposite 1.
