Each of the blank space represents a non-negative value; hence it could have a value between 0 and 9 inclusive.
(A) 33_,_42 {Considering 33_, the possible numbers we get will be from 330 to 339 among which we do not have any squares of a positive integer as 18^2 = 324 and 19^2 = 361}
(B) 45_,_88 {Considering 45_, the possible numbers we get will be from 450 to 459 among which we do not have any squares of a positive integer as 21^2 = 441 and 22^2 = 484}
(C) 57_,_36 {Considering 57_, the possible numbers we get will be from 570 to 579 among which we have 576 = 24^2 and considering _36, the possible numbers we get will be from 036 to 936 among which we have 036 = 6^2}
(D) 80_,_03 {Considering 80_, the possible numbers we get will be from 800 to 809 among which we do not have any squares of a positive integer as 28^2 = 784 and 29^2 = 841}
(E) 82_,_60 {Considering 82_, the possible numbers we get will be from 820 to 829 among which we do not have any squares of a positive integer as 28^2 = 784 and 29^2 = 841}
Ans. (C)

Can this question be solved just by looking at the last digit of the number? Only the number ending with 6 can be a square.
