A class that contains methods that can change instance variables is called a _____________ class.Group of answer choicesstaticmutableimmutableabstractpublic

The correct answer to the question is "mutable."

Explanation:

1. A mutable class is one that allows its instance variables to be changed after the object is created. This means that the state of an object can be modified through its methods.
2. In contrast, an immutable class prevents any changes to its instance variables after the object is instantiated. This is typical of classes in certain programming languages that emphasize safety and stability, like Java's String class.
3. The other options (static, abstract, and public) refer to different characteristics of classes, such as visibility and behavior, but they do not specifically pertain to an object's ability to change its internal state.

Thus, the appropriate choice to fill in the blank is mutable.
