What guidelines does the least principle provide? A take any object; now from any method in that object, the principle tells us that we should only invoke methods that belong to any components of the object. 就任何对象而言，在该对象的方法中，我们只应该调用该对象的任何组件的方法。 B take any object; now from any method in that object, the principle tells us that we should only invoke methods that belong to objects passed in as a parameter to the method. 就任何对象而言，在该对象的方法中，我们只应该调用被当做方法参数传递进来的对象的方法。 C take any object; now from any method in that object, the principle tells us that we should only invoke methods that belong to the object itself. 就任何对象而言，在该对象的方法中，我们只应该调用该对象本身的方法。 D take any object; now from any method in that object, the principle tells us that we should only invoke methods that belong to any object the method creates or instantiates. 就任何对象而言，在该对象的方法中，我们只应该调用该方法创建或实例化的对象的方法。

B) Take any object; now from any method in that object, the principle tells us that we should only invoke methods that belong to objects passed in as a parameter to the method. The Least Principle, also known as the Least Knowledge Principle or the Principle of Demeter, states that a given object should have minimal knowledge of the other objects it interacts with, including only invoking methods on objects that are directly passed in as parameters to its methods.
