    Answer : Option B

    Explanation :

    The following is the example program to explain "using bit fields inside an union".

     

    #include 
 union Point 
 {
    unsigned int x:4; 
    unsigned int y:4;  
    int res;
 };  

 int main()
 {  
     union  Point pt;   

      pt.x = 2;    
      pt.y = 3;   
      pt.res = pt.y;     
      
      printf("\n The value of res = %d" , pt.res);   
    
      return 0; 
 } 
  // Output: The value of res = 3
