The answer is all of these
The battle of bull run was the first major battle of the civil war. the union had lost.

The answer is C.
I got this answer by the process of elimination. Not A - Because it is a holy book consisting of the words of God (or Allah) that were revealed to Muhammad in a cave.

Not D - Muslims constantly follow the Quran because it is their holy book, much like a Christian with the Bible or a Jew with the Torah.
Hope this helped!
