    Answer:  (d) 48 

    Explanation:-
    225 is a perfect square of 15, 
    169 is a perfect square of 13, 
    144 is a perfect square of 12, 
    100 is a perfect square of 10, 
    64 is a perfect square of 8

    48 is not a perfect square of any number. 

    Then, the odd number is 48. 

    Hence, the correct answer is option (d) 48.
