The property that is followed in most of these pairs is the sum of the digits of the first number and the sum of the digits of the second number.
However, for (52, 95): The sum of the digits of 52 is 5 +2 = 7, and the sum of the digits of 95 is 9+5 =14. The difference between the sums is 7.
Conclusion: Thus, (52, 95) does not follow the same property as the others. Therefore, the correct answer is (C) (52, 95)
