Methods that require you to use an object to call them are called methods.1. accessor
2. instance
3. internal
4. static

The answer is "Option 2".

Methods of instance are needed to construct an object of their class and needed to call. In java, the static method can be called without generating a class object. and other options are not correct that can be explained as follows:

In option 1, Accessor is a function that is used to set the value of private fields that's why it is not correct.In option 3, Internal is a keyword that is used to provide accessibility to function.In option 4, Static is a keyword that is used with a class, method, and variable. This keyword is used to share the same variable or method to the class. That's why it is not correct.
