PLEASE HELP (Giving Good Points!) How did conferring the status of dhimmi help the Ottoman Empire?

1. It helped Muslims gain a better social status and access to all of the benefits in the empire

2. It helped to unify it by allowing Muslims and non-Muslims to live in peace

3 It gave non-Muslims the opportunity to convert to Islam without paying a special tax

4. It kept non-Muslims from being conquered by the Ottoman Empire.
