Program Description Answer

An instance of a class refers to each object created from a class.

Hence, the correct answer is option “C”.

Explanation of Solution

Instance of a class:

  • • A class is defined as a group of user defined data structure that consists of fields, properties, and methods that can perform several operations for all instances of the class.
  • • A class acts as a declaration of a real world entity.
  • • An object of a class cannot be directly created until it has its own properties and methods.
  • • When an instance of a class is created, a separate memory block is being created in the memory.
  • • A class is a blue-print which describes how an instance of the class is created.

Explanation for incorrect options:

Reference:

To pass the instance of a class to a method parameter, a reference is used.

Hence, the option “A” is wrong.

Example:

Example contains the real time information regarding an event.

Hence, the option “B” is wrong.

Event:

An event is defined as a specific task performed to attain a target output.

Hence, the option “D” is wrong.
