Option A is the correct answer for the above question
Explanation:
The object is used to take memory for the class member and functions because the class is the only structure which defines the types of the member for that class. The class object is used to reference a member of the class. The object of the class is known as an instance of the class and the one object variables value is different from the other objects variable value for the same class. So the object is used to holds the instance field because the object is used to initialize the value of the variable of the class. So the attributes associated with the class object can be called the instance field . The above question also asked the same and the answer is Instance field which is stated from the option A. Hence Option A is the correct answer while the other is not because--
Option B states about instance method which refers to the method of a class for which that object is created.
Option C states about the fixed attributes which are not the correct answer.
Option D states about class instances which refer to the object of the class.
Constraints are associations between multiple variables which set boundaries for the values these variables can take at the same time. They put limit on values that variables can accommodate.
