Why Did Romanization Have Less Effect in the Eastern Provinces

Why did Romanization have less effect in the eastern provinces than in the western provinces?

A) The religious beliefs of the peoples in the eastern provinces condemned those who succumbed to Roman influence.
B) The peoples of western Europe were more impressed by Roman culture than were peoples in the more advanced east and were therefore more open to adopting Roman customs.
C) Hellenistic-Near Eastern culture had long been firmly entrenched, thus making it difficult for Romanization to have much sway.
D) Unlike the peoples of the western provinces, who all spoke Latin, the multilingual east found it difficult to understand and relate to Roman law, literature, and customs.
