What is wrong with the following code？（）  
class MyException extends Exception {}  
public class Qb4ab {  
public void foo（） {  try {  bar（）；  } finally {  baz（）；  
} catch （MyException e） {} 
}  
public void bar（） throws MyException {  
throw new MyException（）； 
}  
public void baz（） throws RuntimeException {  
throw new RuntimeException（）； 
 }  
}  

A . Since the method foo（） does not catch the exception generated by the method baz（）， it must  declare the RuntimeException in its throws clause.
B . A try block cannot be followed by both a catch and a finally block.
C . An empty catch block is not allowed.
D . A catch block cannot follow a finally block.
E . A finally block must always follow one or more catch blocks.
