正确答案： D
解析：变量t是一个Person对象，但是它是用Teacher实例化的，这个问题涉及到java的编译时多态和运行时多态的问题，就编译时多态来说，t实际上是一个Person类，这涉及到类型的自动转换（将一个子类的实例赋值给一个父类的变量是不用进行强制类型转换，反之则需要
进行强制类型转换，而且被赋值的变量实际上应该是一个子类的对象），如果对t调用了子类中新增的方法则造成编译时错误编译将不能通过，而在运行时，运行时系统将根据t实际指向的类型调用对应的方法，对于本例来说，t.print(10)将调用t实际指向的Teacher类的对应方法。在java中，可以用一个子类的实例实例化父类的一个变量，而变量在编译时是一个父类实例，在运行时可能是一个子类实例。
