  4. Question is ambigous, One can choose various property of the number to select a odd one.
    For example
    (1)addition of digit is odd or even
    (2)addition of digit is prime or compound number
    (3)number is odd or even
    (4)No. of prime factors: odd,even,prime or dissimilar

    List of such property is endless and hence answer can be different
