  What is a benefit of organizing code into modules?

  A. improves overall performance

  B. reduces the length of code

  C. enables code to be multifunctional

  D. enables the reuse of code

  Correct Answer: D

  Modules are a way to build independent and self-contained chunks of code that can be reused. Developers typically use modules to divide a large project into smaller parts. This way the code is easier to read and understand, and each module can be developed in parallel without conflicts. A Module is packaged as a single file and in addition to being available for integration with other modules, it should work independently. A module consists of a set of functions and typically contains an interface for other modules to integrate with. It is essentially a library and cannot be instantiated. Note: A module is just a set of functions in a file.
