What occurs when a parent choice is nested and a child choice is selected?

When a parent choice is nested and a child choice is selected, the parent choice is automatically selected. This relationship is critical in many selection scenarios, particularly in data-gathering systems or forms where hierarchical choices are present.

In these scenarios, the parent choice typically provides a grouping or category under which the child choices fall. Therefore, selecting a child choice implies that the user has also selected the broader category represented by the parent choice. This mechanism ensures consistency and clarity in the selection process, signaling to the user that their selection is affirmative within a specific context implied by the parent category.

The other choices do not accurately reflect this hierarchical relationship between parent and child choices. For instance, stating that only the child choice is affected disregards the interdependence of the selections. Similarly, saying the parent choice remains untouched or is locked does not account for the automatic selection that usually accompanies the selection of a child choice. Thus, choice C effectively captures the dynamic nature of selection in nested scenarios.
