    B 115 Correct Answer Incorrect Answer
    C 129 Correct Answer Incorrect Answer
    D 161 Correct Answer Incorrect Answer

    Solution

    The logic followed here is as follows: Third number = (First number)┬│ - (Second number)┬▓

    First row: 5┬│ - 4┬▓ = 125 - 16 = 109

    Second row: 8┬│ - 7┬▓ = 512 - 49 = 463

    Third row: 6┬│ - 9┬▓ = 216 - 81 = 135
