Answer:
a. They needed the income from taxes assessed on non-Muslims.
Explanation:
The main reason why the Abbasid dynasty encouraged, but did not force, non-Muslims to convert to Islam was because they needed the income from taxes assessed on non-Muslims. Based on this, we can conclude that their reasons were mostly economic ones. If the Abbasid empire became homogeneous, they would not be able to enjoy the benefits that a diverse empire gave them.
