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.
