From the both positions of dice, it is clear that-
No. 6 has 2,3,4,5 as its adjacent faces.
Hence, 1 is opposite to 6.
Rotating the first dice along face containing No. 6, we get Second position of dice.
Hence, 4 is opposite to 3 and 2 is opposite to 5.
Hence, When 5 is at the top, 2 is at the bottom.
Therefore, Option A is correct.
