What happens to nested components when committing a change?

When committing a change, only the selected nested components are updated or modified. This behavior allows for more granular control over what gets deployed or committed, enabling users to focus on specific changes rather than committing everything associated with a parent component. It enhances efficiency, as developers can make targeted updates without affecting unrelated parts of the application, which is particularly useful in larger projects with complex hierarchies of components. This selective approach helps to minimize errors or unintended updates, as it empowers users to choose precisely what to deploy based on their immediate needs.

In contrast, the other options suggest broader actions that don't align with the specific and flexible nature of nested component management within a deployment process. For instance, saying that the entire parent file is updated regardless of selected components undermines the very functionality designed to ensure only relevant changes are committed. Similarly, the idea that nested components cannot be committed separately or that unselected changes are simply ignored does not accurately reflect the capability to manage specific commits efficiently within nested structures.
