Which of the following statements is true about modules in programming?

Modules are essential tools in programming that promote organization and reusability of code. When a statement asserts that modules are designed to hold related code components, it highlights a fundamental principle of modular programming.

By grouping together code that serves a similar purpose or functionality into a module, programmers can create a clear structure for their applications. This means each module can encapsulate specific functionality, making it easier to manage complexity in larger codebases. When a module contains related components, developers can work on them independently, enhance maintainability, and simplify debugging processes, as changes in one module typically do not directly impact others.

This design philosophy benefits collaboration among developers, allows for better documentation, and helps in unit testing, where software can be tested in segments defined by module boundaries. This modular approach is foundational to many programming languages and frameworks today, contributing to improved organization and scalability of software projects.
