Which of the following best describes the term 'modularization' in ABAP?

The term 'modularization' in ABAP refers specifically to decomposing a program into reusable code blocks. This approach promotes better organization and management of code, allowing developers to break complex tasks into smaller, manageable pieces. Each of these code blocks or modules can be developed, tested, and reused independently, which enhances the efficiency of the development process.

By using modularization, developers can avoid duplication of code, which is not only beneficial for maintaining the code but also improves readability and reduces the likelihood of errors. This practice is critical in large-scale applications where different parts of the program need to interact seamlessly. In ABAP, various techniques such as function modules, methods, and subroutines are employed to achieve this modular structure, streamlining the overall application architecture.

The choices regarding combining all codes into a single block, creating documentation, or implementing security measures do not align with the concept of modularization. These aspects of programming are important, but they do not capture the essence of creating reusable components that is central to modularization in ABAP.
