Most Civil War battles were fought in? A. north B. west C. East D. all the areas equally.
Clearly the answer is not A. Only a handful of battles, most famously Gettysburg, were fought in northern states, though a number of major battles were fought in the border states of Maryland, Kentucky, and Missouri, all of which remained in the Union. As for choosing between B and C, if one includes the Trans-Mississippi theater in the count, there were more battles fought in the West. If one only includes the theatre of operations designated the Western theatre by the United States Army, then the answer is C. But there were more battles (at least those designated as battlesites by the National Park Service) in the Western part of the country than the East, so the best answer is probably B.
