Final answer:
The question is about the principles of Object-Oriented programming (OO). The principles that do not include concurrency are inheritance, encapsulation, and polymorphism.
Step-by-step explanation:
OO Principles
The question is about the principles of Object-Oriented programming (OO).
Inheritance
OO principle of inheritance allows objects to inherit properties and behaviors from other objects.
Concurrency
Concurrency is not a principle of OO programming. It refers to the ability of a program to execute multiple tasks at the same time.
Encapsulation
Encapsulation is an important principle in OO programming that involves packaging data and methods into a single unit called a class.
Polymorphism
Polymorphism allows objects of different classes to be treated as objects of a common superclass. It enables objects to be used interchangeably.
