Abstraction, Encapsulation, Polymorphism and Inheritance are the essential features of a OOP Language.
Abstraction is used to hide the inner details of the data in the programming languages.
Abstract classes can be created using a programming language supporting OOPS.
Encapsulation is used to bind the data and functions together in the form of bundles.
Polymorphism is used to implement the functions having same signature but different functions.
Inheritance is implemented in the programs to inherit the properties of one class to the another class or objects. The concept of polymorphism is used in inheritance to reuse the functions or methods.
Hence, option 2 is correct.

Essential Features of Object-Oriented Programming (OOP)
Object-oriented programming (OOP) is characterized by several key features that facilitate robust software development. Among the options presented, let's analyze the essential features.
1. Abstraction and Encapsulation
- Abstraction: This feature allows programmers to focus on the high-level functionality of an object without needing to understand the intricate details of its implementation.
- Encapsulation: It refers to bundling the object's data and methods that operate on that data, restricting access to some components. This promotes data hiding and protects object integrity.
2. Strictly-Typedness
- While strictly-typedness ensures that variables are explicitly defined and checked at compile-time, it is not an essential feature of OOP. Many OOP languages are dynamically typed, allowing for flexibility.
3. Type-Safe Property Coupled with Sub-type Rule
- Type safety ensures that operations are performed on compatible types, reducing runtime errors. The subtype rule allows for polymorphism, but it is not a core requirement that defines an OOP language.
4. Polymorphism in the Presence of Inheritance
- Polymorphism: This allows objects to be treated as instances of their parent class, enabling methods to be defined in a way that they can operate on objects of different types.
- Inheritance: It facilitates code reusability and the establishment of a hierarchical relationship between classes.
Conclusion
Given the analysis, the correct answer is option B (1 and 4). Abstraction and encapsulation are fundamental to OOP, while polymorphism, when combined with inheritance, enhances flexibility and functionality. Strictly-typedness, while beneficial, is not essential to the definition of an object-oriented programming language.
