Using a SubVI offers significant benefits in terms of code reusability. SubVIs allow developers to encapsulate functionality within a separate, modular block of code, which can then be called from multiple locations within a project or across different projects. This modularity ensures that once a SubVI is created and tested, it can be reused anywhere, reducing duplication of effort and minimizing the chances of introducing errors.

By employing SubVIs, developers can create a library of reusable components, which can streamline the development process and enhance maintainability. If changes are needed, they can be made in one place—the SubVI—rather than in every instance where that code is used. This not only saves time and effort but also improves code clarity and organization.

Other options, while they may have some relevance, do not embody the primary advantage of SubVIs. For example, improved execution speed is not inherently guaranteed by the use of SubVIs; in some cases, there may be a slight overhead in calling a SubVI. Similarly, while SubVIs can help in reducing hardware requirements indirectly by lowering complexity, that is not their main purpose. Finally, increased dependency on the main VI contradicts the idea of modular design, as good practice promotes reduced coupling
