    C (34, 35, 23) Correct Answer Incorrect Answer
    D (39, 78, 24) Correct Answer Incorrect Answer

    Solution

    The pattern followed here is: The sum of the first and second digits of the first number is multiplied by the sum of the first and second digits of the third number to obtain the second number. (68, 84, 42) → (6 + 8) X (4 + 2) = (14 X 6) = 84 (53, 35, 25) → (5 + 3) X (2 + 5) = (8 X 7) = 56 (72, 81, 54) → (7 + 2) X (5 + 4) = (9 X 9) = 81 (34, 35, 23) → (3 + 4) X (2 + 3) = (7 X 5) = 35 (39, 78, 24) → (3 + 9) X (2 + 4) = (12 X 6) = 72 Hence, option D is the answer as it does not follow the given pattern.
