Answer:
E. rule
Explanation:
A Rule is a statement which sets out a concept or norm and acts as a guideline to direct or enforce action or behavior.
Rules can be classified into four basic categories:
- Folklore: Unpublished rules which are implicitly recognized and communicated through actions.
- Guidelines: widely established and suggested procedures that require flexibility in interpreting and using them.
- Mandates: written commands which wouldn't be disregarded under any conditions and whose infringement is punishable.
- Policies: written rules that indicate a predicted activity and which, under certain conditions, may be permitted or tolerated.
