    B 23 : 29 Correct Answer Incorrect Answer
    C 89 : 165 Correct Answer Incorrect Answer
    D 51 : 56 Correct Answer Incorrect Answer

    Solution

    The pattern followed here is: 47 : 75 → (4x7) + 47 = 28 + 47 = 75 23 : 29 → (2x3) + 23 = 6 + 23 = 29 89 : 165 → (8x9) + 89 = 72 + 89 = 161 ≠165 51 : 56 → (5x1) + 51 = 5 + 51 = 56 Thus, '89 : 165' is the odd pair. Hence, the correct answer is (C).
