Rearrange the following sentences to form a coherent paragraph:
This allows a programmer to specify the structure and behavior of an object-oriented program.
Object-Oriented Programming (OOP) is a programming paradigm based on the concept of "objects," which can contain data and code.
A central tenet of OOP is the concept of a "class," which acts as a blueprint for creating objects.
The key advantage of this approach is that it models real-world entities, making complex systems easier to manage and debug.

Correct option is A

Option (a) 2, 3, 1, 4 is the correct order of the given sentences.
Explanation (why this order is correct):
• 2 must come first because it introduces and defines OOP and explains the core idea of “objects.”
• 3 logically follows by introducing a key concept within OOP— class—as a blueprint for objects.
• 1 comes next because “This” refers to the class concept, explaining what it allows a programmer to do (specify structure/behaviour).
• 4 fits best as a conclusion because it states the main advantage/outcome of the approach—real-world modeling and easier management/debugging.
