    Answer : Option C

    Explanation :

    fmod(x,y) - Calculates x modulo y, the remainder of x/y.
    This function is the same as the modulus operator. But fmod() performs floating point divisions.

    Example: 

      #include
          #include <math.h></span>
    int main ()
    { 
    printf ("fmod of 3.14/2.1 is %lf\n", fmod (3.14,2.1) );

    return 0;

    }

    Output:
    fmod of 3.14/2.1 is 1.040000
