Answer:

The correct answer to the following questions is:

1.) Option e.) answer = gradStudent.CalculateAvg(87.2, 90);

6.) Option a.) ToString( ).

2.) Option d.) data, behavior.

Explanation:

There are two types of methods in every programming language.

1. User-defined methods -These methods are those which is defined by the user and these methods where the user wants.

2. Built-in methods - These methods are those which are already defined in these language. Only users can call these methods.

Overloaded method - These functions are those functions which have the same name but different in the argument list.
