    (11,144,9)(11,144,9)​​

    D.

    (13,131,5)(13,131,5)

    Correct option is B

    Given:
    (7,127,6)(7,127,6)
    (8,129,5)(8,129,5)
    Logic: Square number of 1st and 3rd number and then multiply 1st & 3rd number and then add the resultant.
    Explanation:
    (7,127,6): 7×7=49,  6×6=36
                         7×6 = 42
    Then, add 49+36+42 = 127
    (8,129,5): 8×8= 64, 5×5=25
                     8×5 = 40
    Then, add 64+25+40 = 129
    Similarly,
    Option A.) (9,168,3): 9×9=81, 3×3=9
                       9×3=27
    Then, add 81+9+27= 117(Does Not follow)
    Option B.) (10,156,4): 10×10=100, 4×4=16
                             10×4= 40
    Then add, 100+16+40= 156(Follows)
    Option C.) (11,144,9): 11×11=121, 9×9=81
                      11×9=99
    Then, add 121+81+99 = 301(Does not follow)
    Option D.) (13,131,5): 13×13=169, 5×5=25
                         13×5=65
    Then, add 169+25+65 = 259(Does not follow)
    Thus, Option B is the correct answer.
