B) belief in religious equality of all people. Let's take a look at the available options and see what makes sense and what doesn't given our knowledge of Sikhism, Hinduism, and Islam. A) belief in a single god. * Islam believes in a single God. So this is obviously not the correct answer. B) belief in religious equality of all people. * Not entirely certain about this option. My first impression is that it's the correct answer simply because the radical believers in Islam seem so focused on the "non-believers" needing to be converted, or killed. So I did a quick google search on Sikhism and its tenets. And immediately found the following "Somewhat unique among the world's religions, Sikhism rejects the notion that any religion, even theirs, holds a monopoly on ultimate spiritual truth." So this is definitely the correct answer. C) belief in existence of a single founder of the religion. * Islam believes in the founder being Muhammad. So this is also not the correct answer. D) belief in the rebirth of souls after death. * Islam believes in an after life and Hinduism believes in reincarnation. So this is also a bad choice.
