Select from following answers:
Run ALTER INDEX REBUILD WITH (ONLINE = ON)
Run ALTER INDEX REORGANIZE
Rebuild the table
Nothing, the index fragmentation is at a safe level
Generally, you should reorganize indexes if the fragmentation is between 5 and 30 percent. You should rebuild the index if the fragmentation is over 30 percent. Remember, these values provide a rough guideline for determining the point at which you should switch between ALTER INDEX REORGANIZE and ALTER INDEX REBUILD. However, the actual values may vary from case to case. It is important that you experiment to determine the best threshold for your environment.
