Best Answer Explained in Below-:

The correct answer is B) C, as it is not an object-oriented programming (OOP) language. C is a procedural programming language, which means it relies on the use of functions to operate on data. In C, the program is structured around procedures or routines, and data and functions are treated as separate entities. This approach emphasizes a sequence of actions to be taken, limiting the capacity for representing complex data structures as objects.

In contrast, C#, Java, and C++ are all object-oriented languages. They support the key concepts of OOP: encapsulation, inheritance, and polymorphism.

- **C#** is built around objects and classes, making it a fully-fledged OOP language, primarily used in .NET development.
- **Java** is also object-oriented, focusing on the principle of "write once, run anywhere," and uses classes and objects as foundational building blocks.
- **C++** extends C by adding object-oriented features, allowing for both procedural and object-oriented programming paradigms.

Thus, C stands apart as a procedural language, contrasting with the other options that are fully object-oriented, making C the correct answer to the question.
