Answer:
B. consider religion less important to their lives
Step-by-step explanation:
It seems to be a very basic principle, at least in most cases, that as a country is becoming more and more secular, the religion is becoming less and less important, and the religious authorities lose big chunk of power. The reason for this is that the secular states are clearly separating the politics from the religion, thus the religion doesn't have any political power. As the religious authorities lose their power, and the people become more educated and free, gradually they leave the religion behind, and either just respect it as part of their tradition, or totally abandon it and move toward atheism. This can easily be seen in the majority of the well developed countries.
