What is a characteristic of parent rows in a project management sheet?

In a project management sheet, parent rows serve significant organizational functions, and their characteristics align with specific project management processes. The correct answer indicates that parent rows are read-only. This is primarily because parent rows are typically used to summarize or aggregate information from child rows, which represent specific tasks or details.

By being read-only, parent rows help ensure that the integrity of the data they reference is maintained. Users can still view the aggregated data at a glance without modifying the overall structure of the project hierarchy.

While editable features might apply to certain tasks within the hierarchy, the primary function of a parent row is to serve as a summary for its children, thereby preserving the logical flow and clarity essential for effective project management.

In contrast, other characteristics like being able to delete or manage dependencies may apply to tasks within the project, but they do not define the key characteristic of the parent rows in this context. The focus on being read-only highlights the protective nature of project hierarchies to maintain project clarity and data consistency.
