What is a key advantage of using a modular approach for application composition?

A modular approach for application composition is advantageous primarily because it enhances maintainability and allows for independent development and deployment of components. When applications are designed in a modular fashion, each module can be developed and tested independently, which streamlines both the development process and ongoing maintenance.

This approach fosters a clearer separation of concerns, making it easier to manage changes. If one module needs to be updated or replaced, it can often be done without needing to modify or redeploy other parts of the application. The ability to deploy updates to individual modules also minimizes downtime and enhances the overall agility of the development lifecycle, enabling teams to respond more quickly to user needs and changing market demands.

The other options do not align with the benefits of a modular approach. For instance, reduced development speed is contrary to the aim of a modular strategy, which typically aims to improve efficiency. Increased maintenance complexity also does not apply, as modularization generally simplifies rather than complicates maintenance tasks. Lastly, tighter coupling is not a feature of a modular system; rather, the goal is to achieve loose coupling between modules to further enhance their independence and reusability.
