    Answer : Option A

    Explanation :

    if(a here a is a float variable and 0.7 is a double constant. The float variable a is less than double constant 0.7. Hence the if condition is satisfied and it prints 'C'
    Example:

     #include 
 int main()
 {   
     float a=0.7;   
     printf("%.10f %.10f\n",0.7, a);    
     return 0;
 }

    Output:
    0.7000000000 0.6999999881
