Program Description Answer

The collection of programming statements which specifies the methods and fields of that a specific type of object have is called as “Class”.

Hence, the correct answer is option “A”.

Explanation of Solution

Class:

In simple words class can be defined as the template or blueprint that describes the state or behavior of the object. Class is also defined as the idea or plan or structure of a real-world entity.

  • Class defines the properties or methods of the objects which is represented by abstraction.
  • An object exhibits the methods and properties defined by the class.
  • Therefore, object is known as instance of class.

Explanation for incorrect options:

b. Method:

Method is a function that belongs to an object. Method is a member of a class. It is used to perform operations on data attribute objects.

Hence, the option “B” is wrong.

c. Parameter:

Parameter is a value passed as an argument to the methods.

Hence, the option “C” is wrong.

d. Instance:

An instance of a class is an object created from a class. The methods can be accessed with the help of the instance.

Hence, the option “D” is wrong.
