The correct answer is - Reforms allowed religious freedom with a tax on non-Muslims.
Suleiman the Magnificent, is often considered the greatest emperor of the Ottoman Empire. Unlike his predecessors, he was a great diplomat, reformed the empire in many ways, was much more tolerant towards the other religions and ethnic groups, and was also a very educated man.
One of his reforms included the religious tolerance and the attempt to eliminate the discrimination towards the Christian and Jewish population in the empire. That was well accepted by the Christians and Jews of course, though part of the reform was that they also have to pay tax for that kind of freedom. Still, most of the people were very happy to not be discriminated and persecuted, so they didn't payed too much attention on the taxation for the time being.
