1, 2, 3, 4, 5 and 6 are written on different faces of a dice. Three different positions of the same dice are shown below. Find the number on the face opposite to the one showing '4'.

​

6 is common face in first and second positions.

From first and second positions,

So, 5 is on opposite face of 4.

Thus, option C is correct.
