To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Flat - This option is incorrect because the Requirements Grid view does not display requirements in a flat format. Instead, it allows you to organize requirements in a hierarchical structure.
Option B) Hierarchical - This option is incorrect because the Requirements Grid view already displays requirements in a hierarchical format. It does not need to be enabled for this purpose.
Option C) Flat non-hierarchical - This option is correct because the Requirements Grid view enables you to display requirements in a flat non-hierarchical format. This means that the requirements are displayed as a list without any nested or hierarchical structure.
Option D) Flat-hierarchical - This option is incorrect because it combines the concepts of both a flat and hierarchical format, which is not applicable to the Requirements Grid view.
The correct answer is C) Flat non-hierarchical. This option is correct because the Requirements Grid view allows you to display requirements in a flat non-hierarchical format.
