In the First Dice and Second dice, Letter C is common. The left letter will be opposite to each other writing them clock-wise starting from B.

Option 1 → E is opposite to A, not C. Option 2 → We left with the only F who is opposite to C. Option 3 → B is opposite to D, not C. Option 4 → A is opposite to E, not C. Hence, the correct answer is "F".
