The question asks about a key benefit of modularizing code into functions.

Since the provided answer options are not included in the data (the answer_options field is empty), we cannot perform a full option-by-option analysis. However, we can discuss the given answer and the general rationale behind modularization.

Consider the stated answer: 'Improves readability and reusability'. This aligns with common software engineering principles. Modularity breaks a program into smaller, well-named units, making the code easier to read and understand because each function has a clear purpose. It also promotes reusability because functions encapsulate behavior that can be invoked from multiple places in the codebase, reducing duplication and making maintenance easier.

That said, in a typical multiple-choice setup, other plausible options might include ideas like 'increases execution speed', 'reduces memory usage', or 'eliminates the need for comments'. Each of these statements is generally less accurate or context-dependent. Modularization does not inherently speed up execution; in some cases it can even introduce small overhead. It does not inherently reduce memory usage and it does not remove the need for good documentation or comments. These distinctions are important for evaluating why readability and reusability are the most robust benefits across diverse scenarios.

In summary, with modularization, the core advantages people most reliably observe are improved readability and reusability due to clear separation of concerns, named abstractions, and the ability to reuse well-defined utilities across the codebase.

If you obtain the missing options later, you can contrast each alternative against these principles: does it reference readability, reusability, maintainability, testability, or coupling/cohesion? That will help determine which option best captures the key benefit.
