    Answer: (a) 53 

    Explanation:-
    The square root of 169 = 13, 
    The square root of 121 = 11
    The square root of  64 = 8 .

    Then, 13 + 11 + 8 
     = 32, 

    The square root of 144 = 12,
    The square root of  196 = 14,
    The square root of 81 = 9. 

    Then, 12 + 14 + 9 
     = 35 

    Same as, 
    The square root of 289 = 17, 
    The square root of 441 = 21, 
    The square root of 225 = 15, 

    Then, 17 + 21 + 15 
      = 53

    Then, the value of ? is 53. 

    Hence, the correct answer is option (a) 53.
