B. the conquest of non-Christian areas by Christian colonial powers.

Explanation:

This is the main reason why Christianity is so geographically widespread. Christianity worked together with colonialism and imperialism as a tool to advance the interest of superpowers. This was first seen in America, as Europeans colonizers brought Christianity with them. The process was repeated in the next centuries all across the world, including large regions of Asia and Africa.
