Answer 2

Answer:

THE ANSWER TO THIS QUESTION IS SINGLE VALUED ATTRIBUTES OR CONSTANTS

Explanation:

Attributes: These are the entities used to store some values.Their values may remain constant or may change during the operations.Let us suppose we are considering some features like color , torque , engine capacity , model etc of an object car the attributes could store the values blue , 120 Nm , 1200 cc , SUV , etc .

Single value attributes or constants: These are those attributes which remain constant independent of any operations.As in the above mentioned example feature like engine capacity cannot be changed for a particular car and hence it is a single value attribute of the car.

Variables: These are those attributes which keep changing with operations on the particular object.As in above example the feature like the market value of the car keeps decreasing with time , increased usage etc hence its a variable attribute of the car.
