It is a mechanism in the principle of OOP in which one class acquires the property of another class.*1 pointAbstractionInheritancePolymorphismEncapsulation

The mechanism described in your question pertains to Object-Oriented Programming (OOP). Let's analyze the terms:

1. Abstraction: This is the process of hiding the complex reality while exposing only the necessary parts. It's about simplifying complex systems.

2. Inheritance: This is the principle where one class (called a child or derived class) acquires the properties and functionalities of another class (called a parent or base class). It allows for code reusability and establishes a hierarchical relationship between classes.

3. Polymorphism: This allows methods to do different things based on the object it is acting upon, essentially enabling one interface to be used for a general class of actions.

4. Encapsulation: This principle focuses on bundling the data (attributes) and methods (functions) that operate on the data into a single unit or class. It restricts direct access to some of the object's components.

Given the definitions, the mechanism where one class acquires properties from another class is clearly Inheritance.

Final Answer

Inheritance is the correct term that indicates a class acquiring properties from another class in OOP.
