Which of the following statements correct about the below program?

 #include
  int main() 
  {   
      union a   
      {       
          int i;       
          char ch[2];     
     };  
     union a u1 = {512};   
     union a u2 = {0, 2};   
     return 0;
 }

1:	u2 CANNOT be initialized as shown.
2:	u1 can be initialized as shown.
3:	To initialize char ch[] of u2 '.' operator should be used.
4:	The code causes an error 'Declaration syntax error'
