Which of the following can be described as the process of creating two versions of an object so that users at a lower level of security cannot access information at a higher level of sensitivity?

A.
Polymorphism

B.
Polyinstantiation

C.
Inference

D.
Aggregation

Explanation:
Polyinstantiation is a feature of object-oriented programming thatprevents subjects at a given level from accessing higher sensitivity information.Polyinstantiation is a process of interactively producing more detailed versions ofobjects by populating variables with different values or other variables. It isoften used to prevent inference attacks.
