Form is called as the . . . . . . . .

object
dot member access operator
instance of a class
class

The correct answer is: C. instance of a class

A form is a user interface element that allows users to interact with an application. It is a type of object, and as such, it is an instance of a class. A class is a blueprint for creating objects. It defines the properties and methods that an object can have. When you create a form, you are creating an instance of the Form class.

The other options are incorrect for the following reasons:

  • Option A: An object is an instance of a class. A class is not an object.
  • Option B: The dot member access operator is used to access the members of an object. It is not a type of object.
  • Option D: A class is a blueprint for creating objects. It is not an object itself.
