Hello Haleymcelmurray 

 The most important reason for Assyria’s military successes was its use of new technologies (C)

Reason: Assyria was very advanced in technology and used them to their advantage. Most others countries didn't have the knowledge they had and where at a disadvantage. 

Hope This Helps!
