public class foo {  static String s;  public static void main (String[]args) {  system.out.printIn (“s=” + s);  } }  What is the result?()
A

 The code compiles and “s=” is printed.

B

 The code compiles and “s=null” is printed.

C

 The code does not compile because string s is not initialized.

D

 The code does not compile because string s cannot be referenced.

E

 The code compiles, but a NullPointerException is thrown when toString is called.
